Loosen the captive screw holding the faceplate to the mounting plate.

Pull the lower part of the faceplate to remove it from the mounting plate.

Loosen the screw (captive) holding the wire cover and remove the wire cover.

Pull wires through the hole in the mounting plate and secure the mounting plate to the wall

(or onto an electrical box for line voltage wiring) using the enclosed wall anchors and screws.

Wire the thermostat to the heating system and, if necessary, connect the remote input.

Once wiring is complete, re-install the wire cover.

Use the switches located at the back of the faceplate to configure your thermostat according to your application.

Install the batteries.

Mount the faceplate on the mounting plate and tighten the screw.

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.

Direct wiring to the circulator

Installation

240 V

Must be installed by a competent person. To ensure

your safety, make sure the mains power is switched OFF

before accessing wiring.

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.
