1 OUTPUT

•

POWER LIMIT INPUT

•

+ 1 HIGHER SIGNAL OUTPUT

•

DAY-NIGHT MODE ( T160 ONLY )

TO OPEN THERMOSTAT COVER

•

Remove security screw on left side of thermostat cover.

•

Open up by pulling on the left side of thermostat.

THERMOSTAT INSTALLATION

A) Location:

1- Shouldn’t be installed on outside wall. 2- Must be installed away from any heat source. 3- Shouldn’t be affected by direct sun radiation. 4- Nothing must restrain vertical air circulation to the thermostat.

B) Installation:

1- Pull out cables 6” out of the wall. 2- Wall surface must be flat and clean. 3- Separate the thermostat and the base by pulling cover on the left side (same

as the security screw.) 4- Insert cable in the central hole of the base. 5- Align the base and mark the location of the two mounting holes on the

wall. 6- Install shields in the wall. 7- Insert screws in mounting holes on each side of the base.

DO NOT OVERTIGHTEN!

8- Open the cable protection 1 1/4 inch more or less. 9- Strip each wire 1/4 inch. 10- Insert each wire according to wiring diagram. 11- Reinstall the cover ( right side first ). 12- Install security screw.

SETPOINT ADJUSTMENT KNOB LIMITATION

Note: To limit the rotation of setpoint knob, adjust setpoint to desired value, then insert stoppers in appropriate holes.

Horizontal model:

S1,S10 = No limitation S3 à S8 = Setpoint limitations

Vertical model:

S7,S10 = No limitation S1 to S7, or S12: Setpoint limitations

REMOTE SENSOR

It is possible to use a remote sensor ( for duct or room application) by connecting it to pins no. 6 and 7. Inside sensor must be disconnected by removing jumper J4 inside the thermostat.

Characteristics of remote sensor 47 KΩ.

DAY-NIGHT MODE

An external contact closing between terminals 6 and 8 activates night mode. A LED on the thermostat flashes continuously indicating night mode. By pressing the button on the thermostat, day mode is reactivated. The thermostat returns to night mode when pressing again the button, or automatically after a 4 hours delay.

Note: Terminals 6 and 8 can be connected together between thermostats.

POWER LIMIT INPUT

An external DC voltage applied between terminals no. 9 (+) et 6 (-), limits the power permitted to output 1 only when this output is programmed as heating. The following table gives the relationship between input voltage and the allowed power for output 1.

10 volts 0 %

Note: Terminals 6 and 9 can be connected together between thermostats.

HIGHER SIGNAL OUTPUT

Output no 3 (terminal no. 10) produces a DC voltage 0 to 10 volts . This signal can be connected with signals from all other thermostats. Resulting voltage corresponds to higher demand of heating or cooling, depending of programming at each thermostat. This signal can also be used to control a modulating 0 to 10 VDC actuator. Resistive load between 2 KΩ and 100 KΩ is recommended.

Note: Terminals 6 and 10 can be connected together between thermostats.
