  • Page 3: Introduction

    During power loss its internal memory saves settings for unlimited time, and the clock continues to run for at least 24 hours. An extension of Carrier’s proven line of thermostats; it provides separate setpoints for heating and cooling in addition to humidification and dehumidification.

  • Page 4: Installation Considerations

    INSTALLATION CONSIDERATIONS Power This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C terminals) of the low−voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections. Rh and Rc are connected via PCB breakout jumper.
  • Page 5 There are programmable and non−programmable models for all applications. They can be configured for AC or HP, 1−or 2−speed compressor, and for Hybrid Heatt installations, allowing it to be used in place of all Carrier thermostats. Programmable Thermidistat Controls may be configured as non−programmable if user desires.
  • Page 6 ELECTRICAL OPERATION HAZARD Failure to follow this warning could result in personal injury or death. DO NOT connect furnace HUM terminal directly to Thermidistat Control HUM terminal. This will bypass furnace safety controls. See Low Voltage Wiring Diagrams and notes for proper connection.
  • Page 7 Remote Indoor Temperature Sensor A remote temperature sensor may be used with the programmable model, where it is desirable to install the Thermidistat Control in a limited access location while measuring the temperature in the living space. The remote room sensor may be used as a stand alone or average with local sensor.

Default is On. Option 16 — Maximum Cycles Per Hour This selection limits the number of cycles per hour that the Thermidistat Control allows the system to operate.
  • Page 33 Option 18 — Backlight Configuration When OF (off), the backlight will be lit for 10 seconds after a button is pressed. After 10 seconds of no button presses, the backlight turns off. When On, the backlight will normally be on and dim in appearance. The backlight brightness becomes brighter when a button is pressed.
  • Page 34 cooling equipment when the dry contact is closed. See Wiring Diagrams for more information. Default is OF (off). Option 19 — Dry Contact Configuration (non−programmable models only) OF — The dry contact is always de−energized. ON — The dry contact will operate as a DH relay. This relay is reverse logic. When the humidity level is above the dehumidify setpoint, the dry contact D1−D2 will be opened.

  • Page 45: System Start−Up And Checkout

    SYSTEM START−UP AND CHECKOUT The Thermidistat Control is designed with a built−in installer test capability. It allows easy operation of equipment without delays or setpoint adjustments to force heating or cooling. To enable installer test mode, press and hold the fan button for 15 seconds.
  • Page 46 non−programmable models, pressing the features button shall toggle the state of the dry contact. In a heat pump application, when the mode is set to “em heat” the auxiliary heat will turn on for 3 minutes. The clock display will count down from 180 to 0 during this test.
  • Page 47 If the programmed schedule is to be used, make sure the triangle icon next to the FOLLOW SCHEDULE icon is turned on. Pressing the Schedule button will cycle the triangle icon through the FOLLOW SCHEDULE, HOLD and VACATION selections. If fixed temperatures are desired, use SCHEDULE button to turn on arrow icon next to HOLD.
  • Page 48 When changing Vacation settings, the soft keys are used to choose the selection to be adjusted and the UP/DOWN buttons are used to change the setting. Humidify setting may only be changed when heat mode is selected and Dehumidify setting may only be changed when cool mode is selected. Humidity Control Features The various humidity control features of the Thermidistat Control are explained below.
  • Page 49 2. Auto Humidify Thermidistat Control will automatically adjust the humidity setpoint according to the outdoor temperature. As the outdoor temperature decreases, the humidity setpoint also decreases. Settings ranging from 1 to 9, 1 being the lowest and 9 the highest, will be visible to the homeowner. See Fig.
  • Page 50 Dehumidification Dehumidification is done only during cooling. Depending on type of equipment used, compressor speed, blower speed, setpoint adjustment, and equipment cycling are modified to provide added dehumidification. A dehumidification setpoint (separate from humidification setpoint) is available to the homeowner. It can range from 46% to 66% relative humidity.
  • Page 51 setpoint is adjusted upward by 2% per degree of overcooling. For example, a cooling setpoint of 76_F/24_C and a dehumidify setpoint of 60% is equivalent to a cooling setpoint of 75_F/24_C and a dehumidify setpoint of 62%. This dehumidify setpoint change is internal to the Thermidistat Control and is not shown on the display.
  • Page 52 To Select Dehumidification (programmable − between NORMAL, COOL TO, and OFF) Press the soft key below the dehumidify icon button to bring up dehumidify selections. Dehumidify options are only available when in Cooling mode. When system is in AUTO mode, dehumidify options are available if the last system operation was a call for cooling.
  • Page 53 − output is turned On when no dehumidify demand exists and is turned OFF when demand exists. Carrier FK and FV series variable−speed fan coils, all variable−speed furnaces, and select single and multi−stage furnaces with the dehumidify connection have dehumidify inputs which connect directly to Thermidistat Control dry contact.
  • Page 54 Vacation Setpoints A special set of temperature and humidity setpoints exist which are active in vacation mode. They are adjustable by the homeowner, are exclusively for vacation mode, and are remembered from one vacation selection to the next. See Table 3 for default values. Table 3 –...

  • Page 55: Operational Information

    dehumidify setpoint is accessible by pressing the soft key below the dehumidify icon when the box is around the cooling setpoint. OPERATIONAL INFORMATION Timers Five−Minute Compressor Timeguard This timer prevents compressor from starting unless it has been off for at least 5 minutes.
  • Page 56 Defrost When defrost occurs in a Hybrid Heat system, the furnace will operate during the defrost cycle. At the end of the defrost cycle, the furnace and heat pump will be de−energized while the fan is energized for 2 minutes allowing the heat exchanger to cool down.
  • Page 57 Heat/Cool Setpoints (Desired Temperature) A minimum difference of 1_ and maximum of 6_ is enforced between heating and cooling desired temperatures. This is done by allowing 1 setting to “push” the other, to maintain this difference. This difference is adjustable via Configuration Option 11.
  • Page 58 Programmable Fan (programmable models only) The fan output can be programmed based on period of the day. When programming for each day and period the fan can be set to On or AUTO. If the fan button is pressed to change from On to Auto or vice versa when programmable fan has been enabled, the manual change will only remain in effect until the next program period, when the programmable fan setting will be changed per the scheduled setting.
  • Page 59 See Wiring Diagrams for more information. Relays This thermostat uses latching relays. When the thermostat loses power, the relays will remain in their last position until power is restored and all relays are reset to their correct position. Out of the box, the outputs may appear to be On when the thermostat is not powered.

  • Page 60: Troubleshooting

    TROUBLESHOOTING If the display module doesn’t power up after power is applied, check the Rc/Rh and C terminals for 24VAC. If 24VAC is present, check the voltage between Vg and V+. This voltage will be approximately 12−20VDC. If voltage is present, check the polarity to make sure it is wired correctly.
  • Page 61 E5 − If Thermidistat Control cannot properly read humidity, E5 will be displayed. Replace Thermidistat Control. If both Humidify and Dehumidify have been set to OF, the humidity value will be shown as “−−” when viewed from the humidity menu, but no E5 will be shown in the display. Table 4 can be used as a troubleshooting tool for determining which outputs will be active for a particular configuration and each operating mode.
