Menu setting Description 0 Internal sensor To control the ambient temperature using the internal (built-in) sensor 1 Room To control the ambient temperature using the AC144-03 temperature sensor (the internal sensor is not used) 2 Air return To control the temperature at the air return using the AC146-410 temperature sensor (the internal sensor is not used) 3 Air supply To control the temperature at the fresh air supply using the AC146-410 temperature sensor (the internal sensor is not used) 4 Automatic changeover To control the ambient temperature using the internal sensor. The AC146-410 temperature sensor is used for automatic changeover. See section 5.5.1. 5 Limited cooling To use the outdoor air for cooling whenever possible. The AC146-410 temperature sensor is used to measure the outdoor air temperature. The internal temperature sensor measures the room temperature which is then compared with the setpoint. If the room temperature is lower than the setpoint, the air intake damper remains closed. If the room temperature is higher than the setpoint, the latter is then compared with the outdoor temperature. If the fresh air temperature is lower than the setpoint by more than 3°C (5.4°F), the damper opens to allow cool air in. 4.3 Output 1 Output 1 is used to control a damper. It controls heating when the thermostat is in heat mode or cooling when the thermostat is in cool mode. The following table shows the different default modes, the different output types for Output 1, and their corresponding settings in the configuration menu. Menu setting 1A & 1A2T models 1F & 1F2T models 0 Cool / 0-10 V analog Cool (max. of 10 min. refresh) (24 V tri-state floating) 1 Heat / 0-10 V analog Heat (max. of 10 min. refresh) (24 V tri-state floating) 2 Cool / 2-10 V analog (max. of 10 min. refresh) 3 Heat / 2-10 V analog (max. of 10 min. refresh) 4.3.2 Minimum Opening The minimum damper opening can be set between 0 and 50 %. Note: It is not recommended to set the minimum damper opening to 0 % (fully closed) when a duct heater is connected to Output 2 or 3. 4.3.3 Opening time (1F and 1F2T models only) The damper opening time can be set between 80 and 160 seconds. 4.4 Output 2 (models TH150-1A2T and TH150-1F2T) Output 2 controls heating only, regardless of the thermostat's mode. When the thermostat is in heat mode, Output 2 is activated as soon as Output 1 reaches its full capacity. When the thermostat is in cool mode, Output 2 is activated when the measured temperature drops below the setpoint. The following table shows the output types for Output 2 and their corresponding settings in the configuration menu. Set the following configuration parameters: · Default mode · Output type (1A and 1A2T models only) · Minimum opening · Opening time (1F and 1F2T models only) 4.3.1 Default Mode / Output Type The default mode (heat/cool) is used for the following: · The default mode is the thermostat's mode at power-up. · The default mode is the active mode when the N.O. changeover contact is open (see section 5.5.2). · When configured as a contact (see section 4.5), Output 3 controls either heating or cooling depending on whether the default mode is set to heat or cool respectively.

Menu setting Description 0 Not used 1 24 VAC pulsed (triac) / 1 sec. cycle (e.g., 24 V SSR such as Aube relays RT850 or RT850T) 2 24 VAC pulsed (triac) / 10 min. cycle / direct action (e.g., N.C. thermal valve) 3 24 VAC pulsed (triac) / 10 min. cycle / reverse action (e.g., N.O. thermal valve) 4 24 VAC pulsed (triac) / 15 min. cycle (e.g., mechanical relay such as Aube relays RC840 or RC840T) 5 N.O. contact (The contact closes when Output 1 reaches or exceeds set percentage. See section 4.1.) When any setting between 1 and 4 is selected, Output 3 controls heating only, regardless of the thermostat's mode. 4.7 DIP Switches Three switches at the back of the control module are used to select various options. Temperature Display (SW1) Selects the desired temperature display (°C or °F). Access Mode (SW2) Selects the operation mode (NORM) or the configuration mode (MENU). · Place the switch to MENU to access the configuration menu. · Place the switch to NORM for normal display. Output 2 Type (SW6) Sets Output 2 type (Analog or Triac). WARNING: Place the switch according to the type of device (Analog or Triac) connected to Output 2. Failure to do so can result in thermostat damage. 5. Operation When setting 5 is selected, Output 3 controls heating or cooling depending on whether the default mode has been set to heat or cool respectively (see section 4.3.1). For example, if the default mode has been set to heat mode, the contact remains opened when the thermostat is in cool mode. When the thermostat is in heat mode, the contact closes when Output 1 reaches a percentage of its capacity, set via the configuration menu. 4.6 Minimum and Maximum Setpoints The minimum and maximum setpoints are factory-set at 10°C (50°F) and 35°C (95°F). The maximum setpoint can be set between 35°C (95°F) and (minimum setpoint + 1). The minimum setpoint can be set between 10°C (50°F) and (maximum setpoint - 1). 5.1 Power-Up Upon power-up, the thermostat undergoes a series of test before displaying the actual temperature. Note: On the TH150-1F and TH150-1F2T models, at power-up, the message OPEN appears at the top of the screen during the calibration of the damper opening. This can last up to 3 minutes. 5.2 Backlight To turn the backlight on, press any button. The display will illuminate for 12 seconds. 5.3 Temperature Display and Setting The thermostat usually displays the actual temperature. To view the setpoint, press once on one of the buttons. The setpoint appears for 5 seconds and is indicated by the display. During the setpoint display, press one of the buttons to change it. Note: The temperature setpoint is automatically increased or decreased by 1°C (2°F) when the controller switches to heating mode or to cooling mode respectively. For example, if the setpoint is at 25°C (77°F) in heating mode, it will become 26°C (79°F) in cooling mode and will return to 25°C (77°F) when the controller is back in heating mode. 5.4 Output Display The bar graph represents the voltage for an analog output or the duty cycle for a triac output. The bar graph usually shows Output 1 power (% of damper opening). To view Output 2 or 3, press Override for 2 seconds to enter the diagnostic mode. Press Override momentarily to switch between the three output graphs. To exit the diagnostic mode, press Override for 2 seconds or wait for 1 minute for the mode to exit automatically.

If the thermostat is in heat mode, it switches to cool mode when the air supply is cooler than ambient by 5°C (9°F) or more. If it is in cool mode, it switches to heat mode when the air supply is warmer than ambient by 5°C (9°F) or more. Note: Neither the heat mode icon ( ) nor cool mode icon ( ) appears when TH150 is placed in automatic changeover. 5.5.2 Changeover Input The thermostat is in the default mode when the contact between terminals 9 and 11 is open and switches mode when the contact is closed. The default mode is set via the configuration menu . Note: The changeover contact state is ignored if TH150 is configured in automatic changeover or in limited cooling. 5.6 Night Setback The Night Setback (NSB) mode is activated when the contact between terminals 9 and 12 is closed. When TH150 is in the NSB mode, indicated by the ECONO display, the temperature is lowered or raised by the set NSB value depending whether the thermostat is in heat mode or cool mode respectively. The NSB value is set via the configuration menu. Night Setback Override To temporarily override the NSB mode, press the Override button. The NSB mode is lifted for the next 2 hours or until the Override button is pressed again. During the override, the normal setpoint is used and OVERRIDE is displayed. 5.7 Error Codes The following error codes can appear at the top of the display. E1: The internal temperature sensor is defective E2: The internal temperature sensor is shorted E3: The external temperature sensor is defective or not connected E4: The external temperature sensor is shorted 6.
