Thermostat Installation BEFORE YOU BEGIN DETERMINE THE APPROPRIATE INSTALLATION LOCATION FOR THE THERMOSTAT. THE THERMOSTAT SHOULD FACE THE BED AREA OF THE ROOM. After the installation, follow the “Thermostat Configuration” Instructions to correctly configure the thermostat. For installation of a networking thermostat with remote management, refer to the “Network Installation” manual.
Thermostat Installation Thermostat Installation BEFORE YOU BEGIN: Consult PTAC manufacturer’s documentation or use a voltmeter to determine if the PTAC unit outputs AC or DC power (24V). If the PTAC unit outputs AC power, make sure that the jumper on the Wireless Control Card is in the AC position - jumper is connecting “R” and “COM” pins (Default). If the PTAC unit outputs DC power, make sure that the jumper on the Wireless Control Card is in the DC position - jumper is connecting “COM” and “C” pins.
Thermostat Configuration Thermostat Configuration Once the thermostat is powered, thermostat configuration settings will appear on the thermostat screen. Setting the thermostat clock In order to properly operate the PTAC unit: ➤➤ Set the thermostat clock; ➤➤ Enter the room number; ➤➤ Configure the equipment settings; ➤➤ Select Energy Savings Preset; CONFIGURATION BUTTON NOTE: You can access Thermostat Configuration settings by pressing the “Configuration” button.
Thermostat Configuration Thermostat Configuration Entering the room number Configuring the Equipment Settings - Compressor Type Enter the room number by changing the digits on the screen. Leading zeros “0” preceding other digits will be ignored, i.e. Room number “123” should be entered as “00123”.

Thermostat Configuration Thermostat Configuration Configuring the Energy Saving Settings Testing the thermostat Following the thermostat configuration, test if the thermostat is controlling the PTAC unit.
Thermostat Settings Thermostat Settings Accessing the Thermostat Settings FAN ENERGY SAVINGS Thermostat Settings allow customizing the energy savin settings. To access the thermostat settings: ➤➤ Press and hold the “Configuration” button until the first thermostat settings screen (“00”) appears on the thermostat. The thermostat must be turned on to access the thermostat settings.
Thermostat Settings Thermostat Settings 1 2ND STAGE DIFFERENTIAL - HEAT ST STAGE DIFFERENTIAL - HEAT 02-30 20 (0.2°F - 3.0°F; 0.5°F*) Select the difference between temperature setpoint and room temperature before 1st STAGE heating is initiated. 10-20 (1.0°F - 2.0°F*) Select the difference between 1st STAGE heating and 2nd STAGE heating initiation.
Thermostat Settings Thermostat Settings 1ST STAGE DIFFERENTIAL - COOL INCIDENTAL OCCUPANCY THRESHOLD 02-30 00-60 (0.2°F - 3.0°F; 0.5°F*) Select the difference between temperature setpoint and room temperature before 1st STAGE cooling is initiated. (05*) Select the minimum period of time (in minutes) for which occupancy needs to be detected to enter guest occupancy mode.
Thermostat Settings Thermostat Settings NIGHT OCCUPANCY THRESHOLD FORCED 2ND STAGE HEATING 00-60 00-60 (01*) Select the minimum period of time (in minutes) for which occupancy needs to be detected in order to consider the room occupied during the “Night Occupancy”period. When occupancy is detected while room is considered unoccupied during the “Night Occupancy” period, the thermostat will instantaneously switch to occupied mode for a duration of “Night Occupancy Threshold” selected here.
Thermostat Settings Thermostat Settings NIGHT OCCUPANCY START NIGHT OCCUPANCY END 00-23 00-23 26 (21*) Select the start time (in hours - 24-hour clock) for “Night Occupancy” (09*) Select the end time (in hours - 24-hour clock) for “Night Occupancy” If occupancy is detected for a period of time longer than the “Night Occupancy Threshold” during “Night Occupancy” period, the thermostat will disable the occupancy sensor and consider the room occupied until the end of the “Night Occupancy” period.
Thermostat Settings Thermostat Settings TEMPERATURE RECOVERY TIME RECOVERY TEMPERATURE - HEAT 00-60 62-82 (25*) Select the maximum time allowed for a PTAC unit to attain temperature as defined by Heat and Cool “Recovery Temperature”; (66°F) Select the room temperature in °F that a PTAC unit will have to attain within the selected “Temperature Recovery Time” when there is a need for heating.
Thermostat Settings Thermostat Settings TEMPERATURE SETBACK DELAY - HEAT MINIMUM SETBACK TEMPERATURE 00-120 52-72 (20*) Select the time delay (in minutes) before the thermostat will initiate the temperature setback and allow the room temperature to drop to the setback temperature after the room becomes unoccupied. This feature prevents initiating temperature setback prematurely while the guest is still in the room but in an area where occupancy cannot be detected by the occupancy sensor.
Thermostat Settings Thermostat Settings TEMPERATURE SETBACK DELAY - COOL MAXIMUM SETBACK TEMPERATURE 00-120 72-92 (20*) Select the time delay (in minutes) before the thermostat will initiate the temperature setback and allow the room temperature to raise to the setback temperature after the room becomes unoccupied This feature prevents initiating temperature setback prematurely while the guest is still in the room but in an area where occupancy cannot be detected by the occupancy sensor.
Thermostat Settings Thermostat Settings RECOVERY TEMPERATURE - COOL MINIMUM SETPOINT 62-82 64-84 34 (75°F) Select the room temperature in °F that a PTAC unit will have to attain within the selected “Temperature Recovery Time” when there is a need for air conditioning. (65°F) Select the minimum setpoint in °F that a guest can select.
Thermostat Settings Thermostat Settings MAXIMUM SETPOINT AUTO CHANGEOVER SETPOINT OFFSET 60-82 00-04 (80°F) Select the maximum setpoint in °F that a guest can select. (01°F*) Select the difference between the guest-selected setpoint and the heat and cool setpoints. This feature allows to configure the minimum difference between heat and cool setpoints in order to avoid excessive use of the compressor.
Thermostat Settings Troubleshooting SETBACK SETPOINTS / AUTO-RESTORE Thermostat is not controlling the PTAC unit. Verify the status of the red light on the Wireless Control Card; ➤➤ The red light is off The control card is not powered.
