- The device should be installed by a qualified electrician.
- Before starting the controller, the user shoud measure earthing resistance of the electric motors as well as the insulation resistance of the cables.
- The regulator should not be operated by children.
WARNING
- The device may be damaged if struck by a lightning. Make sure the plug is disconnected from the power supply during storm.
- Any use other than specified by the manufacturer is forbidden.
- Before and during the heating season, the controller should be checked for condition of its cables. The user should also check if the controller is properly mounted and clean it if dusty or dirty.

DESCRIPTION OF THE DEVICE
EU-i-1M module is intended for controlling a three- or four-way mixing valve with the possibility of connecting additional valve pump. The controller features weather-based control, weekly control schedule and it may cooperate with a room regulator. Another asset of the device is return temperature protection against too cold water returning to the CH boiler.
Functions offered by the controller:
- smooth control of a three- or four-way valve
- pump control
- return temperature protection
- weekly control and weather-based control
- compatible with RS and two-state room regulators
Controller equipment:
- CH boiler temperature sensor
- valve temperature sensor
- return temperature sensor
- external weather sensor
- wall-mountable casing
PRINCIPLE OF OPERATION
- Control light 1 – COMMUNICATION – it informs about current status of the module. In the event of an alarm, the control light remains on. During standard operation it flashes. If there is no communication, the light goes off.
- Control light 2 – PUMP it indicates pump operation.
- Control lights 3 and 4 CLOSING/OPENING – they inform about valve closing or opening
INSTALLATION
The controller should be installed by a qualified person.
WARNING
Risk of fatal electric shock from touching live connections. Before working on
the controller switch off the power supply and prevent it from being
accidentally switched on.
WARNING
Incorrect connection of wires may damage the regulator.
NOTE
Plug RS cable to RS socket labelled RS while connecting EU-i-1M valve module
to the main controller, controlling additional valves via RS communication.
Example installation schemes:
1. Valve
2. Valve pump
3. Valve sensor| 4. Return sensor
