13. Installing controller
Connecting external alarm device:
1. controller
2. external alarm device
3. relay
13.15 Connecting mixing valve actuator
WHEN CONNECTING THE MIXING VALVE ACTUATOR, MAKE SURE TO
AVOID BOILER OVERHEATING WHICH MAY OCCUR AT LIMITED BOILER
WATER FLOW. NOTE THE VALVE POSITION CORRESPONDING TO THE
MAXIMUM OPENING TO ENSURE HEAT TRANSFER FROM
THE BOILER WITH THE VALVE FULLY OPEN.
The controller is compatible with mixing valve actuators with limit switches
only. Do not use any other actuators.
Use actuators with valve opening time from 90 to 255 seconds.
Connecting mixing valve:
• connect mixing valve temperature sensor,
• connect mixing valve pump,
• start controller and enable mixing valve in the service menu
Service settings > Mixing valve 1 settings
• enter correct valve opening time in the mixing valve service settings (time
is specified in the actuator data plate, e.g. 120 seconds).
• connect controller power supply and start the controller to activate the
mixing valve pump,
• determine the direction of actuator opening/closing. Switch to manual
control at the actuator housing and determine the position, in which the
temperature in the mixing valve circuit is maximum (corresponds to 100%
ON position of the controller) and valve position, in which the mixing
valve circuit temperature is minimum (corresponds to 0% OFF position of
the controller). Note the position for verification purposes,
• disconnect the controller power supply,
Heating and ventilation
• connect the mixing valve actuator with the controller in accordance with
the instructions provided by the valve actuator manufacturer. Do not
mistake opening and closing direction,
• connect the controller power supply and switch to stand-by mode,
• check, if the mixing valve opening and closing cables are not switched
and select: Manual control > Mixing valve 1 open = ON to open the
mixing valve. When opening the actuator, the temperature at the mixing
valve sensor should increase. Otherwise, disconnect electrical power sup-
ply of the controller and switch the cables. (Note: it may also be caused by
incorrect valve installation - check manufacturer instructions).
13.16 Connecting room temperature controller
The controller is compatible with ecoSTER TOUCH auxiliary panel which may
function as::
• room thermostat,
• boiler control panel,
• alarm signaling device,
• fuel level indicator.
NOTE: USE MIN. 0.5 MM CONDUCTORS FOR 12V AND GND

CONNECTIONS OF THE ROOM TEMPERATURE CONTROLLER.
Maximum cable length should not exceed 30 m. For higher lengths use cables
with the cross-section over 0.5 mm
• Four-conductor connection. Connect in accordance with the wiring
diagram.
• Two-conductor connection. Connect using external power supply
+12VDC min. 400 mA. Room temperature controller power supply points:
Connect GND and VCC to the external power supply, and connect D+ and
D- as shown in the wiring diagram.
