To reset user setting will be necessary to push the buttons + and – together for 10 seconds (the message RE flashing is displayed).

PRODUCT DATASHEET
According to 811/2013 Rule, the class of temperature controller and contribution to seasonal space heating energy efficiency in % are the following:

Class	Contribution	Description
V	+3%	Chronothermostat.
VI	+4%	Chronothermostat combined with the external probe; installed on boiler equipped with modulating burner
VIII	+5%	Zone manager kit combined with 3 Chronothermostat; installed on boiler equipped with modulating burner

The RC22OTRF remote controls are compliant with: – 2014/53/EU (RED) (Electromagnetic Compatibility Directive) RC22OTRF must comply to the above-mentioned Directive,so CE mark is printed on the user manual:

WARNING
Wiring must conform to technical norms, specifically:

the electrical conductors for connecting the remote control to the boiler must go through small channels different from those of the mains (230 V), as they are fed at a low safety voltage.
The installation of the device must be carried out ONLY by qualified person.

Warning: disconnect the power to the boiler before carrying out installation.
In no case can the manufacturer be held responsible if the warnings and instructions given in this booklet are not followed.

INSTALLATION

Choose the most appropriate place for installation in order to guarantee the correct device functioning. It is recommended to install the device at a height of approx. 150 cm from the floor, in a place away from doors, windows or heat sources that could affect the room temperature.
Remove the front of the Chrono-Thermostat by rising with a screwdriver inside the hole below.
Fix the back of the Remote Control to the wall with the set of screws supplied.
Connect the device to the boiler with the OT (COM) terminal,for Open Therm communication, as indicated on the label located inside the back, using a non-polarized bipolar cable < 50 m (Recommended section: 2×0.75mm2).
Note: AUX (IN) input can be connected to a free contact, with a non-polarized bipolar cable < 10 m, of auxiliary remote control devices (GSM, IoT, Home Automation, Zone, …). Closing it allows the start of pre-established states, programs and sets that can be set via parameters. Closing it allows, only for HEATING MODE, the start of pre-established states, programs and sets that can be set via parameters. If WFC03 is connected for remote manage by APP the AUX input doesn’t work.
Refit the front of the Chrono-Thermostat making sure to centre it on the rear part.
Once ended the above indicated procedure, it will be possible to connect the power to the boiler.
