  • Page 20: Terminal Settings

    Terminal Settings Changes to relay and output terminal actions are made in the Installer Menu. NOTE: When the SMART 3000 calls for heating or cooling, the SMART 3000 will drive both the relays and the 0 to 10V outputs simultaneously. This way the SMART 3000 can call a circulating water pump via the relays as it controls room temperature with the valves if needed. 0 to 10V Outputs To permit the control of modulating heating and cooling valves as well as variable speed DC fan motors or variable capacity HVAC systems the SMART 3000 has been fitted with three 0 to 10V outputs. The 0 to 10V outputs in the SMART 3000 are PI (Proportional Integral) controlled. This control method provides the most accurate and cost effective way to control heating and cooling valves by ensuring set temperatures are reached as quickly and efficiently as possible while reducing temperature overshoot. As the SMART 3000 is fitted with both relays as well as 0 to 10V output to control HVAC systems, there may be some slight disparity between the thermostat display and the 0 to 10V outputs actions. The SMART 3000 displays the relay actions, not the actions of the 0 to 10V outputs on the LCD. In most cases these are very closely matched. However, as the 0 to 10V outputs have the capability...
  • Page 21 Figure 8 A1 – Cool This output is used to control a cooling valve. A2 – Heat This output is used to control a heating valve. A3 – Fan This output is used to control a variable speed fan or a variable capacity AC system. If the fan mode is set to Auto speed the 0 to 10V output will vary between these two values based on calculated demand.
  • Page 22 selected the 0 to 10V output will be fixed at 6.6V DC. High speed is set to 10V DC. The Installer Menu provides the following settings for the control of the three 0 to 10V outputs. Span This is the setting for the outputs maximum value. It sets how aggressive the 0 to 10V will move for a given temperature change. The range is 0 to 9°F degrees (0 to 5°C degrees) . Time Interval Time interval sets the running average calculation time. The smaller the number the faster the 0 to 10V output will respond to room temperature changes. The range is 10 to 300 seconds.
  • Page 23 Maximum Value (Fan A3) output only When controlling 0 to 10V fans sometimes it is necessary to limit the fan speed to reduce noise or to protect ducting. The fan output has a high voltage limit setting so regardless of the user selected speed (High, Medium or Low) or thermostat selected auto speed, the 0 to 10V output will not exceed this pre-set high limit. belimo™ 6 Way Valve Belimo™ manufactures an actuator that is in full cooling at 2V, off at 6V and full heating at 10V. To use this type of actuator with the SmartSense SMART 3000 you must enter the Installer Menu and set valve type to Belimo™ Mode. Figure 9 The heating 0 to 10V output only is used in this mode. Information on the Installer Menu can be found later in this manual.
  • Page 24 As with normal valves, the 0 to 10V heating and cooling span settings in the Installer Menu scale the heating and cooling outputs. Factory default is full heating and full cooling 2°F degrees (1°C degree) from setpoint. The heating and cooling span can be adjusted independently to a maximum of full heating and full cooling 6.0°F degrees (3.0°C degrees) from setpoint. The output is linear. NOTE: When using Belimo™ mode, both the A1 Cool and the A2 Heat 0 to 10 outputs are used. Both will provide the same output to the valve. The A3 Fan output will remain unchanged and can be used to control a DC fan or other device.

  • Page 25: Before Applying Power

    before Applying Power Read the sections Commissioning and Advanced Installer Settings. Review each setting and understand how it will affect your installation. Plan ahead for any changes you will make. If this installation will be using ModBus Communications, read the section ModBus Communications on page 36 of this manual. If this installation will be using Remote Sensors, read the section Using Remote Temperature Sensors on page 38 of this manual. COMMISSIONING As with any thermostat, commissioning ensures that the thermostat and the equipment connected to it are operating correctly. Although the SMART 3000 is a multi-functional thermostat, commissioning is quite a simple process. Follow the steps detailed below and use the Troubleshooting Guide on page 63 if you encounter a problem. When the thermostat is fitted to the base plate and when 24V AC power is first applied, the LCD will display the operating screen.

NOTE: Option 36 in the Installer Menu permits you to set the SMART 3000 to automatically reset the indoor fan to Automatic Mode (cycle ON and OFF with heating and cooling) every time the thermostat is turned OFF and then back ON if desired.

  • Page 28: Accessory Functions

    Ventilation Mode If permitted by DIP Sw7 (Table 1 DIP Switch Settings page 11), the user can run the indoor fan only (Ventilation Mode) when the SMART 3000 is OFF by pressing the Fan button. Press the Fan button to cycle between all available fan speeds. Make Up Room and Do Not Disturb buttons When enabled by DIP Sw8 (Table 1 DIP Switch Settings page 11), press these buttons to activate relevant LCD segments and backlight color on the optional outside door station, and to write data to ModBus for BAS system ACCESSORY FUNCTIONS The SMART 3000 has a number of additional capabilities such as communications with Building Automation Systems (BAS) via its ModBus communications port. The SMART 3000 will automatically control temperature setpoints based on occupancy of the room when a suitable door switch and movement sensor is installed. The SMART 3000 will automatically shut down the air conditioning system if balcony doors or windows are left open when the optional door/ window switches are installed. When you wish to see the room status and have an integrated doorbell from the hallway outside the room, the SMART 3000 can be fitted with the optional hall panel.
  • Page 29 Complete System Overview The SMART 3000 is the hub of a complete room comfort and energy control system. As shown in Figure 11, the SMART 3000 accepts door, window and Passive Infra-Red (PIR) contact inputs to automatically control temperature setpoints. The wall controller mounted in the hallway outside of the room provides feedback of the guest's needs to housekeeping plus provides a convenient button to activate the SMART 3000 internal door bell. Figure 11 Occupancy Detection The SMART 3000 has sophisticated logic that when connected to your choice of movement sensors, door and window switches will automatically control the setpoint and mode of the SMART 3000.
  • Page 30 Figure 12 Using part or all of the functions described below are completely optional. The SMART 3000 will function perfectly as a HVAC controller without the door, window or occupancy detection logic enabled. DO NOT APPLY EXTERNAL VOLTAGES TO THESE INPUTS. Window Contact The window contact input (WC) is used to automatically disable the HVAC system if a window is left open. This is done to prevent energy waste by trying to heat or cool an open room. Window input can be set for a Normally Open (switch open when window is closed) or Normally Closed logic (switch closed when window is closed). When the window is left open for longer than the pre-set time (0 to 300 seconds) the SMART 3000 will automatically turn OFF. The text OFF will flash in the LCD to indicate that the remote window (or door switch) is holding the SMART 3000 in OFF mode. The wall controller will prohibit all changes.
  • Page 31 The SMART 3000 will automatically restart once the window is closed. The Installer Menu option 31 Window Input Logic and option 32 Window Input Delay sets the window detection logic in the SMART 3000. Door Switch The Door switch input (DS) is used by the SMART 3000 for two functions. 1. To detect that the door has been opened and then closed to let somebody into or out of the room. 2. To detect if the door has been left open. The door switch input can be set for a Normally Open (switch open when door is closed) or Normally Closed logic (switch closed when door is closed). Installer Menu option 33 Door Input Logic and option 34 Door Input Delay sets the door detection logic in the SMART 3000.
  • Page 32 Door Left Open. When the door is left open for longer than the pre-set time (0 to 300 seconds) the SMART 3000 will automatically turn OFF. The text OFF will flash in the display to indicate that the remote door (or window switch) is holding the SMART 3000 in OFF mode. The SMART 3000 will automatically restart once the door is closed. PIR input A PIR (passive infra-red) movement detector can be directly wired to the SMART 3000 PIR input. As movement is detected by the PIR it will send multiple On/Off pulses to the SMART 3000 every time it detects movement. The SMART 3000 using this data along with door switch data will determine the occupancy status of the room and behave accordingly. NOTE: The PIR must be powered separately, typically from a 12V DC supply. Automatic Occupancy Detection Logic Automatic occupancy detection requires the door switch and PIR input to be wired and working.
  • Page 33 the SMART 3000 will enter Unoccupied mode where the guest’s temperature and mode will be replaced with installer pre-set values. Should movement be detected within the installer pre-set seek time the SMART 3000 will LOCK into Occupied mode. It will no longer rely on continued movement within the room to remain in Occupied mode. Next time the door is opened and then closed again, the SMART 3000 will again begin its occupancy detection process. NOTE: Even when the SMART 3000 is in Unoccupied mode it will continue to use the PIR input to determine room occupancy. For example - a couple may be staying in the room and one leaves the room leaving the other asleep in bed. As the door closes, the SMART 3000 will seek movement and when none is found it will enter Unoccupied mode. As the sleeper wakes and then moves the SMART 3000 will automatically re-enter Occupied mode even though it may have been some time since the door was closed. Installer option PIR Input Delay sets the PIR mode (On or Off) and the seek time value (1 to 15 minutes).
  • Page 34 When the SMART 3000 is in Unoccupied mode, the display will go completely blank except for the words Unoccupied in the top left. If the optional SMART-R- O1H hallway panel is installed its display backlight will go out to let housekeeping know the room is empty. ModBus register 40004 also indicates occupancy status. Doorbell Figure 13 A built-in doorbell feature is included with the SMART 3000 thermostat. This is normally activated by the optional outside door station as described above or via ModBus data link. In circumstances where this is not convenient, the Digital Input (DI) terminals can be reassigned as a doorbell activation switch with the digital input options detailed in the Installer Menu. See page 40. Simply place a momentary volt free switch across DI and Com 0-V terminals to activate the doorbell. Once pressed, the doorbell will chime for about 10 seconds.
  • Page 35 Outside Door Station When coupled with the optional SmartSense door station, the guest has the ability to set the room as Do Not Disturb, call for housekeeping or be alerted to visiting guests with a pleasant doorbell chime. Hotel staff are informed about the room status or guest’s needs by text information displayed on the door station LCD or the door station backlight colors. Figure 14 The connection between the SMART 3000 and the hotel door station is cable fitted with RJ12 plugs. When fitting the door station, the SMART 3000 DIP Sw8 must be ON. The outside door station will flash all LCD segments if DIP Sw8 is in the wrong position. Automatic Day Set Temperature The SMART 3000 can optionally reset the user setpoint and replace it with an installer defined setpoint after the SMART 3000 has been OFF for more than six hours. This will typically happen after one guest has checked out and before the next guest checks in. Option 40 in the Installer Menu defines this function. Select OFF or a value between 59 to 86°F (15 to 30°C).

  • Page 36: Modbus Wiring

    Modbus Wiring ModBus communications unlock many additional functions within the SMART 3000 thermostat. It also permits all modes, functions and controls to be remotely supervised and adjusted from a central location if needed. ModBus object data can be found on page page 48 of this manual. The SMART 3000 will permit the connection of up to 255 devices on a single ModBus node. Radio frequency noises and other interferences will reduce the real world permitted connections to a maximum of 150 to 200 in most cases. ModBus and other communication protocol rely on the quality of cable and good installation practices to ensure reliable communications. ModBus requires the use of shielded cable with the drain grounded in a single location. When using a common power supply or when using a ModBus master that also powers the SMART 3000, be sure the R (24V AC active), C (24V AC common) Data A and B wires are not crossed.
