IV. WIRELESS RECEIVER EU-MW-3
The EU-F-4z v2 regulator communicates with the heating device (or the CH boiler controller) by means of a radio signal
sent to the receiver. The receiver is connected to the heating device (or the CH boiler controller) using a two-core cable.
It communicates with the room regulator using a radio signal.
The receiver has three control lights:
red control light 1 –signalises data reception;
red control light 2 –indicates receiver operation;
red control light 3 –goes on when the room temperature fails to reach the pre-set value –the heating device is
switched on.
NOTE
In case of no communication (e.g. due to no power supply), the receiver automatically disables the
heating device after 15 minutes.
In order to pair the EU-F-4z v2 regulator with the EU-MW-3 receiver, follow these steps:
press the Registration button on the receiver
press the Registration button on the regulator or in the controller menu, using REG screen and pressing .

NOTE
Once registration has been activated in EU-MW-3, it is necessary to press the registration button on the EU-F-4z
v2 regulator within 2 minutes. When the time is over, the pairing attempt will fail.
If:
the EU-F-4z v2 regulator screen shows Scs and the outermost control lights in EU-MW-3 are flashing
simultaneously - the registration has been successful;
the control lights in EU-MW-3 are flashing one after another from one side to the other - the EU-MW-3 module
has not received the signal from the controller;
the EU-F-4z v2 regulator screen displays Err and all the control lights in EU-MW-3 light up continuously - the
registration attempt failed.
V. REGULATOR FUNCTIONS
1. OPERATION MODES
The room regulator may operate in one of three different modes:
Day/night mode –the pre-set temperature depends on the time of day - the user sets a
separate temperature for the day and night (comfort temperature and economical
temperature), as well as the time when the controller will enter each mode. In order to activate this mode,
press EXIT until a day/night mode icon appears on the main screen.
Weekly control mode - the controller enables the user to create 9 different programs divided into 3
groups:
- PROGRAM 1÷3 –daily settings apply to all days of the week
-PROGRAM 4÷6 –daily settings are configured separately for working days (Monday-Friday) and for
the weekend (Saturday - Sunday)
- PROGRAM 7÷9 –daily settings are configured separately for each day of the week.
