• Page 2: Fan coil thermostat specification and installation instructions provide essential guidance for mounting and connecting the device. Remove power prior to separating the thermostat cover from its base to avoid malfunction. The front cover of the thermostat can be lifted after removing the captive screw. Secure the base to the wall using the supplied wall anchors and screws. Make the appropriate connections after pulling the wire through the base hole. Mount the control module on the base and secure it using the screw. Terminal descriptions include various outputs and inputs such as common, 24 Vac, and external temperature sensor. Mode selection can be adjusted using jumper settings on the PC board for operation or programming mode. End users may modify setpoint, control mode, and fan speed if the thermostat is not locked. Digital output signal selection can be configured through jumper settings to link signals to either 24 Vac or common.
• Page 3: Fan coil thermostat specification and installation instructions. When in programming mode, specific symbols are displayed to navigate through functions. The internal temperature sensor can be calibrated with a known thermometer. Minimum and maximum setpoint temperatures can be adjusted within specified ranges. Setpoint locking allows control over user adjustments, with options for locking or unlocking. Control modes include automatic, cooling, heating only, or cooling only. The On/Off function can be enabled or disabled for automatic mode adjustments. Users can select between 2 pipes or 4 pipes for operation. Changeover mode selection affects how the system responds to temperature changes. Calibration for the changeover temperature sensor can also be adjusted.
• Page 4: Fan coil thermostat specification and installation instructions. Set local reheat On/Off or TPM if you have selected 2-pipe control mode. Display switches between “LHt” and “OFF”. Select which signal output you want for AO2. Proportional band for local reheat (AO2) ranges from 0.5 to 5.0ºC. Dead band for local reheat (AO2) ranges from 0.3 to 5.0ºC. Internal/external temperature sensor selection is available. External temperature sensor calibration can be adjusted by comparison with a known thermometer. Proportional band 1 in heating and cooling ranges from 0.5 to 5.0ºC. Set fan speed automatic mode enable or disable.
• Page 5: Fan coil thermostat specification and installation instructions. Time out fan contact displays the automatic shutoff delay value when there is no demand. Select the desired value of the automatic shutoff delay. Fan speed contact displays the speed of the fan. Select which speed contact you want: speed 1, speed 2, or speed 3. Night set back derogation time displays the derogation time in minutes. Select the desired derogation time; if OFF is selected, the thermostat is off when NSB is activated. Heating setpoint during night set back displays the value of the heating setpoint temperature. Cooling setpoint during night set back displays the value of the cooling setpoint temperature. Range for cooling setpoint is 10 to 35ºC [50 to 95ºF] with a default value of 28ºC [82ºF].
• Page 6: Fan coil thermostat specification and installation instructions outline the operation mode and display features. At powering up, the thermostat will light the display and activate all LCD segments for 2 seconds. To illuminate the LCD, press the designated buttons, and it will light for 8 seconds. In operation mode, the thermostat automatically displays the temperature read. To change the temperature scale between ºC and ºF, press both specified buttons for 3 seconds. To display the setpoint, press the button twice, and it will be shown for 5 seconds. When in night set back mode, the NSB symbol is displayed, indicating adjusted setpoints for cooling and heating. To change the control mode, press the designated button to choose from automatic cooling or heating, off, cooling only, or heating only. To change the fan speed mode, press the specified button to select from automatic speed, low speed, medium speed, or high speed. Wiring and schematic details are provided for line voltage and time clock connections.
