DESCRIPTION
The RC-80BZ is a precision digital thermostat designed for 24 VAC single stage heating and cooling systems.
It has the capability of being controlled both locally and by remote control over a Z-Wave network. It offers
programmability, stand-alone operation, and communications with automation systems, utility control systems,
or personal computers over a Z-Wave network. The RC-80ZB is equipped with a "cool blue" backlight display.

The following requirements must be observed for installation in Europe: CE
1. This equipment must be installed in accordance with National wiring rules for the country in which it is
installed.
2. Fuses must be replaced only with IEC rated components.
3. All product labels, instructions and markings relating to safety must be translated to a language, which is
acceptable in the country in which this equipment is to be installed.
INSTALLATION
Before installing this thermostat:
1. Read all of the installation instructions carefully.
2. Read the Owner's Manual carefully.
3. Ensure that this product is suitable for your application.
4. Ensure that wiring complies with all codes and ordinances.
5. Disconnect power to the control transformer to prevent electrical shock and damage to equipment.
6. Select an appropriate location to ensure an accurate temperature reading.
Location
When replacing an existing thermostat, install the RC-80BZ in the same location. If the existing location
doesn't meet the following criteria, choose a new location to mount the RC-80BZ. When choosing a location
for the thermostat:
1. Ensure that the thermostat is mounted 5 feet above the floor and is at least 2 feet from an outdoor wall.
2. Ensure that the thermostat is located in an area where there is adequate air circulation.
3. Do not mount in the path of direct sunlight or of radiant heat generated by appliances.
4. Do not mount behind an outdoor wall, near a fireplace, or in the path of any air ducts.

- Page 2 4. Remove the existing plate or base from the wall. MOUNTING When mounting the RC-80BZ, grasp the thermostat by the sides, avoiding the keys, and unsnap the base from the face. Holding the base to the wall so that the word "TOP" is upright and facing you: 1.
- Page 3 Connect each wire to the terminal strip on the thermostat base per the wiring diagram for your system application - See Figures 4 - 8. Form the thermostat wiring so that the cable lies flat between the terminal strip and the center of the base. Upon completion of wiring the thermostat, push all excess wiring into the hole in the wall.

Page 4: Typical Wiring Diagrams
TYPICAL WIRING DIAGRAMS CAUTION: Be sure to disconnect the power to the control transformer before removing or installing thermostat. Do not short gas valve, fan, heat relay, or cool relay...even momentarily. This will blow a non-replaceable fuse. Do not attempt to hook up to live circuits. An accidental connection to a component on the thermostat circuit board could cause damage to the thermostat. - Page 5 Common wire is required in “cool only” applications Figure 6 - Single stage cool only thermostat * Common wire is required to use the display backlight in the RC-80ZB. Also use if heat, cool, or fan relay cannot supply 15mA to power thermostat, without activating. Figure 7 - Single stage heat/cool thermostat...

*Do not connect RC and RH together. Figure 8 - Heating & cooling with separate transformers CONFIGURING THE BACKLIGHT ON THE RC-80ZB The backlight on the RC-80ZB can be configured to one of three different modes: 1) on for 30 seconds when a key is pressed, 2) always on, or 3) always off. - Page 7 The RC-80BZ thermostat is designed to work with most 4-wire HVAC systems (without a transformer common). However, if the RC-80BZ “resets” (goes blank for a second…then displays all segments for about 5 seconds) when calling for heat or cool, or if the heat, cool, or fan relay cannot supply 15mA to power thermostat without the relay activating, the transformer common wire or the HAI Thermostat Power Supply Module is required.

INSTALLER SETUP This section describes the items that the installer must setup as part of the thermostat installation. The Installer Setup mode is used to configure the general operating parameters of the thermostat. When in Installer Setup mode: 1. The small digits on the top of the display are the item number. 2. - Page 9 24-hour time format non-programmable Fahrenheit 24-hour time format non-programmable When communicating with an HAI controller, the thermostat should be configured as "non-programmable". To disable the clock and filter reminder displays, add “16” to each value. The default setting is 1.

Page 10: Cooling Anticipator
Calibration offset This item is used to raise or lower the current temperature reading by 1 degree Fahrenheit or 1/2 degree Celsius. If this item is set to 30, no change will be made. Each digit below 30 will lower to temperature, and each digit above 30 will raise the temperature. -
Page 11: Heating Anticipator
Heating anticipator This item adjusts the tendency of the thermostat to turn the heating unit off before the desired heat setting is reached. This is done to avoid overheating the air while the walls and furniture catch up. A setting of 0 will disable this feature. -
Page 12: Filter Reminder
(1 = “- 29” to 59 = “+ 29” seconds per day; 30 = No change) The default setting is 30. Note: If an HAI automation system is being used, the controller system time is sent to the thermostat every minute. This adjustment will have no effect. - Page 13 (See Setup Item 03 - "Display Options"). HAI AUTOMATION SYSTEMS The thermostat can communicate with an HAI automation system over a Z-Wave network. The controller can send commands to the thermostat to change mode, cool setting, heat setting, status of fan and hold, and other items.
