4.2 Application Types

The following table shows the different thermostat applications and their corresponding settings in the configuration menu.

Menu setting		Description
0	Internal	To control the ambient temperature using the internal
	sensor	(built-in) sensor
1	Room	To control the ambient temperature using the AC144-03
		temperature sensor (the internal sensor is not used)
		To control the temperature at the air return using the
2	Air return	AC146-410 temperature sensor (the internal sensor is
		not used)
		To control the temperature at the fresh air supply using
3	Air supply	the AC146-410 temperature sensor (the internal sensor
		is not used)
	Automatic	To control the ambient temperature using the internal
4		sensor. The AC146-410 temperature sensor is used for
	changeover	automatic changeover. See section 5.5.1.
		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
	Limited	compared with the setpoint. If the room temperature is
5		lower than the setpoint, the air intake damper remains
	cooling	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.

Set the following configuration parameters:

•Default mode

•Output type (1A and 1A2T models only)

•Minimum opening

•Opening time (1F and 1F2T models only)

4.3.1Default 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.

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.

Menu setting	Description
0	Not used
1	24 VAC pulsed (triac) / 1 sec. cycle
	(e.g., 24 V SSR such as Aube’s 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’s RC840 or RC840T)
5	0-10 V pulsed / 1 sec. cycle (e.g., 3-32 V SSR)
6	0-10 V analog / 1 sec. refresh
	(e.g., SCR controlled device such as a re-heater)
7	0-10 V analog / max. of 10 min. refresh (e.g., valve)
8	2-10 V analog / max. of 10 min. refresh (e.g., damper)

Note: If 0-4 is selected, set the SW6 switch to Triac. If 5-8 is selected, set the switch to Analog (see section 4.7)
