1.3 THERMOSTAT CONFIGURATION
Before installing the thermostat on the wall, it must be set using the dip switches at
the back.
A) Cycles of 15 or 20 minutes
The TH135 offers you heating cycles of 15 or 20 minutes. The
shorter the cycles, the bigger your comfort. However, your system
will be solicited more often.
If you want 15 minute cycles, slide switch #1 upward. If you want
20 minute cycles, slide switch #1 downward.
