4 periods per day or 2 periods per day. Programming can be done for 7 days per week, 5/2 days per week, or 1 day. The programmable thermostat can also be user configured as a non−programmable thermostat.
INSTALLATION CONSIDERATIONS Power This Thermostat 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
Models The Côr 5 and Côr 5C models are temperature control only and the Côr 7 and Côr 7C are temperature and humidity control. All 4 can be configured for AC or HP, 1 or 2−speed compressor, and for Hybrid Heat installations. These thermostats may be configured as non−programmable if user desires.
Page 6
Wiring For all wiring applications, use 22 AWG or larger wire. Continuous wire lengths over 100 ft. (30.5 m) should use 20 AWG or larger. Wire lengths are not to exceed 250 ft. (76 m) per run.
INSTALLATION CAUTION UNIT DAMAGE HAZARD Failure to follow the recommended wiring practices could result in damage to the wall control and personal property. Improper wiring or installation may damage Thermidistat Control. Check to make sure wiring is correct before proceeding with installation or turning on power.
4. Installation Instructions Thermostat Location Thermostat should be mounted: Approximately 5 ft (1.5m) from floor. Close to or in a frequently used room, preferably on an inside partition- ing wall. On a section of wall without pipes or duct work.
Page 9
Thermostat should NOT be mounted: Close to a window, on an outside wall, or next to a door leading to the outside. Exposed to direct light or heat from a lamp, sun, fireplace, or other tem- perature−radiating objects which could cause a false reading. Close to or in direct airflow from supply registers and return−air re- gisters.

select OFF. Some auxiliary heaters require separate G signal to turn on blower. In this case, select On. Select On for geothermal applications. Default is OFF. SW05 − Room Air Temperature Sensing (with Two−Wire Relay Module installed) The remote room sensor may be installed as a single sensor or multiple sensors may be installed for further averaging functionality.
Page 31
Fig. 7 − Remote Room Sensor − Parallel Wiring This selection determines which sensor the Thermostat will use for measuring room air temperature. Room air temperature can be sensed in one of three ways; the local sensor (L) located on the Display Module, the remote room air sensor (r), or the average of local and remote sensors (Lr).

OFF − function is disabled. Auxiliary heat is allowed to operate whenever sufficient demand for heat is available. 5 to 55_F (−15 to 13_C) − Outdoor temperature above which the auxiliary heat is not allowed to operate (unless MODE is set to Emergency Heat). If room temperature falls below 45_F (7_C), the auxiliary heat will be allowed to turn on and will continue to run until demand is satisfied.

Page 38
SW27 —Maximum Heating Setpoint This selection allows the installer to configure the maximum heating setpoint. The range is based on the adjustable deadband value SW11, such that the minimum of the range is 50_F/10_C and the maximum is 90_F/32_C minus the deadband. Default is 88_F/31_C (based on the adjustable deadband default = 2).

OFF – When transitioning from the Away profile to the Home profile, the system will ramp according to the Smart recovery algorithm (30, 60, or 90 minute recovery). Default is On. SW40 —Humidify Fan This selection controls whether humidification can only be done when a heating demand is present.
Page 41
OFF – The fan output (G) is energized when the compressor is on for cool to dehumidify functionality. On – The fan output (G) is de−energized when the compressor is running for cool to dehumidify functionality. In this setup the fan will run at very low speed because a Y/Y2 or Y1/W2 is present but the G signal is not.

if the user has the fan selection set to continuous fan. The fan output will be turned back on in this temperature range if the maximum capacity of auxiliary heat is on due to system demand (auxiliary heat on in response to a defrost signal shouldn’t cause the fan to turn back on).

(when enabled in SW19). It may also control the compressor and blower, depending on equipment type and dehumidify selection choice. The 3 available selections are described below. A mandatory 5 minute blower off delay will be enforced if there has been a call for dehumidification during a cooling call.
Page 50
Fig. 8 − Auto Humidity 3. Dehumidify Off Dehumidification can be turned off completely. This can be done without changing existing setpoints. To Select Dehumidification (programmable − between NORMAL, OVERCOOL, and OFF) From the home screen press Menu > Settings > up/dn arrow to get to Dehumidify > Select then scroll through options with the up/dn arrows.

Refer to fan coil Installation Instructions for details. If FAN is set for continuous operation (Fan On selected), G output is turned off for 5 minutes at the end of each cooling cycle as long as dehumidify demand exists. Like humidify, dehumidify actions are initiated when humidity is 1% above setpoint and are terminated when humidity drops to 1% below setpoint.
Page 52
The furnace dehumidify input acts differently depending on which style of variable speed, select single−stage or multi−stage furnace control you have. Vacation A vacation mode is set specifically for times where the home will not be occupied for an extended period. Vacation mode is created the day your will be leaving as a continuous hold for more than a day.
OPERATIONAL INFORMATION Timers Five−Minute Compressor Timeguard This timer prevents compressor from starting unless it has been off for at least 5 minutes. It can be overridden for 1 cycle by simultaneously pressing FAN and UP buttons. Cycle Timer Based on the selection of 2, 4, or 6 cycles per hour, this timer is set to 30, 15, or 10 minutes.
Page 54
In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes. In Hybrid Heat systems, the minimum on time for the furnace is 5 minutes. If the setpoint is changed, this timer is canceled, allowing the equipment to turn off immediately when the demand is removed.
Page 55
Equipment On Indicators When cooling equipment is on, a COOL icon is displayed. While cooling equipment operation is delayed by the time guard or cycle timer, COOL will flash. The same is true for HEAT icon. When the W is energized in a heat pump or Hybrid Heat system, the “auxiliary heat”...
Page 56
On both the programmable and non−programmable models, when configured as a dehumidify output, it will operate cooling equipment capable of dehumidify function. When configured for dehumidification, the Rc terminal must be connected to one of the dry contact terminals. The other dry contact terminal is connected to the dehumidify terminal on the furnace or fan coil.
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.
