CAUTION: To avoid electric shocks, deactivate your heating system at the
main electrical panel. Read the instructions carefully before disconnecting the
wires.
1.1 Installing a New Thermostat
For a new installation, select a position about 5 feet (1.5 m) above the floor,
where there is good air circulation. The thermostat must be installed on an
inside wall.
Avoid places where there are:
• air draughts (the top of a staircase, an air outlet,...)
• dead air spots (e.g., behind a door)
• direct sunlight
• chimneys or hidden pipes
1.2 Thermostat Installation
Remove the mounting plate from the thermostat.
n Loosen the screw holding the mounting plate to the
thermostat.
o Lift the lower part of the plate to remove it from the
thermostat.
p Loosen the screw holding the wire cover, and remove it.
q Secure the mounting plate to the wall and make the appropriate
connection (refer to section 2).
1.3 Wiring
n
Refer to the diagram. Connect one wire to either therminal and the other
wire to the other terminal.
Connection to a circulator
Connection to a boiler
o Put the wire cover back on.
NOTE: If you have a CT240 telephone controller, refer to section 5.1 for
hook-up.
Before installing the thermostat on the wall, it must be configured
using the dip switches at the back.
2.1 15- or 20-minute Cycles
The TH135 can operate on 15- or 20-minute
cycles. While 15-minute cycles provide
greater comfort, the heating system will be
running more often.
2.2 Temperature Control Modes
You can choose between two temperature
control modes:
Proportional Adaptive Mode
This mode analyses previous cycles in order to define the length of
the upcoming cycle. This mode guarantees optimal regulation of 3
cycles (switch #1 to 20 min.) or 4 cycles (switch #1 to 15 min.) per
hour, regardless of the season.
Ideal for:
• Radiant or convection electrical heating system
• Circulator control in a hot water system
Conventional Mode with Anticipation
This mode turns the system On or Off when the temperature reaches
preset levels. This mode is compatible with all heating systems. It is
recommended for a multi-zone system or when a thermostat directly
controls a furnace equipped with a combustion gas purge cycle of
more than 30 seconds.
