2
a. mounting of the controller:
•
the controller is fixed directly to the wall or to any other support with two screws
(plastic plugs c/w screws are part of delivery)
•
the cables extending from the controller are fixed to the wall with cable clips
b. mounting of the temperature sensor:
•
the sensor is NOT intended for immersion in liquids and installation on
breechings (flues between the boiler and chimney)
•
install the heating water temperature sensor on the bare outlet pipe of the boiler (as
close to the boiler as possible) or on the hot water cylinder
•
install the DHW temperature sensor on the hot water cylinder (cable marked with a
black sleeve)
c. connecting of the power supply cable to the heating water circulating pump:
•
connect the yellow or yellow/green wire (protective conductor) to terminal (
)
•
connect the blue wire to terminal (N)
•
connect the brown wire to terminal (L)
d. connecting of the power supply cable to the DHW circulating pump (marked with a
black sleeve):
•
connect the yellow or yellow/green wire (protective conductor) to terminal (
)
•
connect the blue wire to terminal (N)
•
connect the brown wire to terminal (L)
e. check-up of connections:
•
make sure the connections have been made as indicated and secure the cover of the
pump motor terminal box
f. connection of the controller:
•
upon securing the cables against accidental pullout,
connect the power supply cable
to a 230V/50Hz grounding socket.
IMPORTANT:
At the mounting location of the controller ambient temperature should not
exceed 40ºC.

operational
a. start up:
•
set the left-hand toggle switch (~) to position I,
•
upon energising all the segments of the display light up for ca. 2 seconds,
•
the current temperature, as measured by the sensor is displayed and the controller
operates according to the factory settings (temperature limit of 50°C).
b. description of display functions
•
display continuously on – current temperature, as measured by the sensor,
•
blinking display – temperature setpoint,
•
red LED on – controller is switched to DHW mode
•
green LED on – controller is switched to heating mode
•
dot appears after the second figure – DHW priority is on
c. viewing of DHW temperature
•
for viewing the DHW temperature simultaneously press and release the two switches.
The current temperature, as measured by the DHW sensor will be displayed. After 5
sec. the heating water temperature will return to the display.
