To turn off Holiday function press the button .

USER PARAMETER EDITING

• Press the button for 3 seconds to access user parameters menu.
• Press any other button to exit.

CU – Sliding temperature – Compensation curve

Note: default point set is 0.

Installing the external probe to the boiler the heating system temperature is adjusted according to the outside weather conditions. In particular, as the external temperature increases the system delivery temperature decreases according to a specific compensation curve.

The compensation curve can be set from 1 to 10 according to the following graph:

External temperature (°C)

1. Press the button for 3 seconds until CU is showed.
2. Press buttons and to change the value.

Set the compensation curve to 0 to disable Sliding Temperature adjustment.

Sliding temperature – Parallel curve offset

P2 – Pre-heating function

Important: this function is active only if heating automatic mode has been selected.

When this function is enabled, the device makes the boiler starting before the set hour, in order to reach comfort temperature the soonest even from the very beginning of the time slot (not before 00:00). It is also possible to set a fixed pre-heating slope, in this way, the device considers as comfort temperature adding 3° to set temperature, thus the boiler does not switch off when the set is reached.
During the pre-heating function the room temperature °C symbol flashes. The function ends when the difference between the programmed room temperature and the actual one is less than 0,5°C.

Note: default point set is 0 = Deactivated.

PRODUCT DATASHEET

According to 811/2013 Rule, the class of temperature controller is:

Class| Contribution to seasonal space heating energy efficiency (%)| Description
---|---|---
V| +3%| Chrono-Thermostat
VI| +4%| Chrono-Thermostat combined with the external probe

The RC22.xx remote controls are compliant with: – 2014/30/UE (Electromagnetic Compatibility Directive)

RC22 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

1. 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.

2. Remove the front of the Chrono-Thermostat by prising with a screwdriver inside the hole below.

3. Fix the back of the Remote Control to the wall with the set of screws supplied.

4. 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.

5. 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.
