If the controller is taken into use as a constant temperature controller, the outdoor temperatu-
re measurement is activated here and also inactivated if necessary.
H1 control circuit’s supply water sensor connected to the controller.
The controller uses the TMR room sensor to measure the room temperature. The controller
uses measurement information when it adjusts the room temperature according to set values.
Connect the H1 control circuit room temperature measurement to measurement channel 3 and
the H2 control circuit room temperature measurement to measurement channel 4.
The room sensor (TMR) is connected to measurement channel 3 and the potentiometer (SP) to
channel 4. The potentiometer (SP) can be used to make changes from -5°C to +4°C in the room
temperature setting. The TMR/SP affects the H1 control circuit.
The room compensation unit (TMR/P) measures changes in room temperature and if necessary,
adjusts the supply water temperature so that the desired room temperature is reached.
Use the TMR/P knob to steplessly set the desired room temperature b16°C - .+24°C. The
point in the middle is equivalent to a room temperature of about 21°C. The TMR/P is often already
installed in renovation locations having EH-80. The TMR/P affects the H1 control circuit.
Turn the Home/Away switch to the off mode (status) (contact closes) to make a “Temperature
drop”. Setting the amount of temperature drop: see p. 11. The home/away switch affects cont-
rol circuits H1 and H2.
The controller uses return water meas. information for control and can raise or lower the supply
water temperature if necessary. The controller gives a lower limit alarm if the return water tem-
perature falls under +5°C and an upper limit alarm if the return water temp. rises above 95°C.
Boiler temperature meas. information. Lower limit alarm +45 °C, upper limit alrm +95°C.
Accumulator temp. meas. information. Lower limit alarm +2 °C, upper limit alarm +95°C.
The solar collector’s temperature measurement information.
Make sure that the temperature sensor can be used for this.
The meas. can be labelled. The controller gives a lower limit alarm if the temp. falls below -50°C
and an upper limit alarm if the temp. rises above 130 °C. If the meas. is not labelled, it will read
meas. 3(4, 5) on the display.
Alarm information from a pressure switch connected to the heating network.
Alarm information about burner malfunction
Alarm information from a water circulation pump.
