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.

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.

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.
DAMPER CHANGEOVER INPUT
A) MANUAL CHANGEOVER (Code G = 1 or 2): Output 3 operates generally as
per selected mode on the order code (example: cooling, G = 1). When a contact closes
between terminals 6 and 9, output 3 changes its action (Example: heating). Terminals
6 and 9 can be connected together between thermostats.
Use a diode (Example: 1N4001) as indicated on the wiring diagram. Only one diode is
needed for all thermostats connected together.
Note: Terminals 6 and 9 can be connected together between thermostats.
B) AUTOMATIC CHANGEOVER (Code G = 3): Use a remote sensor (S60 or
S70) for each thermostat, upstream of the damper. T his sensor can be calibrated ( ±
2.0 °C )at the thermostat if needed, using a small screwdriver on the right side of the
thermostat. Indicated temperature increases when rotating the potentiometer
clockwise.
When the supply temperature is below the setpoint, output 3 operates in cooling mode.
When the supply temperature is above the cooling setpoint (setpoint + co), output 3
operates in heating mode.
C) AUTOMATIC CHANGEOVER WITH RECIRCULATION (Code G = 4):
Damper operates as described above in B (automatic reversing), except that, when
supply air temperature is between heating and cooling setpoint for a period more than
25 seconds, damper opens 100 %.
DAMPER 0 TO 10 VDC OUTPUT
Output no 3 (terminal no. 10) produces a DC voltage 0 to 10 volts generally used for
damper control. Minimum value of damper or flow can be adjusted using the C263
programmer from 0 to 100 %. Adjust LL parameter to desired minimum position and
HL to maximum desired position. LL and HL are preprogrammed at 0 (0 volt) and
100% (10 volts) at the factory. Adjusting LL and HL does not affect the effective
proportional band. Example: LL=20%, HL=80%, Pb=0 .9 °C. damper will modulate
from 20 to 80 % on a 0.9 °C proportional band.
Parameter HF is used to adjust the maximum value of damper or flow. This
parameter is active when damper is in cooling mode only. If adjusted to 0, the damper
position will remain at minimum (LL) on a heating demand. If adjusted at a value
higher than the LL value, the damper position will raise proportionally with the
heating demand, up to this maximum value.
