Remote Input Wiring
For a 2-wire connection: no polarity.
The thermostat is equipped with a remote input
which allows connection of a telephone controller or
a home automation system. When a signal is received
through this input, the thermostat will automatically
switch from normal operating mode to Vacation
mode. For details on operating the telephone
controller, refer to the instruction manual.

Conventional mode with anticipation (switch #5)
This mode is compatible with all heating systems.
1. If you change from °C to °F (or vice versa), you will need to reprogram your Comfort, Economy and Vacation settings.
2. For hot water installations, it is recommended to enable this option to activate the pump for one minute every
24 hours to prevent pump seizure.
Programmable Span Selection (switches #1 and #2)
Select the span using switches #1 and #2. The default temperature span is 0.5°C. For example, if the
temperature setpoint is 20°C, the heating system will turn on at 19.5°C and turn off at 20.5°C.
1.4.1
Proportional Adaptive Mode (switch #5)
This mode analyzes previous cycles to define the the next duty cycle. This control mode guarantees optimal
temperature control based on the system’s capacity. To extend the life of the system, a minimum On/Off time
of 10% of the cycle has been implemented.
