Relay 1 is not being used.
Explanation:
On the display:
Not in use
The pumps stop (relay 1's space 73 and 74 opens) and the selected valves close when the
outdoor temperat. is warmer than the "Pump stop" setting. During a stop period the regulator
starts the pumps for a few minutes every day to prevent them from getting stuck (interval use).
The regulator time controls any electric apparatus using the relay, eg. a sauna stove, door
locks. Timing programming is done in clock functions (p. 15). In the timing program's "ON"
mode the relay is activated.
The control mode can also be changed using a GSM
telephone (see p. 20).
The regulator controls relay 1 by time. In the "ON" mode the relay is activated. The "ON"
mode is prevented if the outdoor temperature is colder than the relay 1's set outdoor
temperature limit. (See p. 30). Timing/ outdoor temperature control is suitable for exhaust
fan control

230V actuator
When you have reserved relay 1 for 230V actuator control, the regulator automatically also
reserves relay 2 for 230V actuator control if relay 2 is free. If relay 2 is not free, the regulator
first requests to free relay 2 for 230V actuator control. After this you can begin using
230VAC 3-point control in the "actuator selection" mode (see page 25)

GeothHeatFull
When the control mode selected for relay 1 is "GeothHeatFull", the regulator automatically
reserves relay 2 to control the compressor of the geothermal heating and reserves
digital input 1 for geothermal heating selector switch position information (automatic position =
strip connector 21-22 closed).
Relay 1 controls heating
resistor. The regulator controls the compressor or the heating resistor according to the
accumulator temperature set by the user. The compressor and heating resistor cannot be
on at the same time.
The heating resistor is switched on at the ["GeothHeatAcc." setting -hysteresis - 10°C]
temperature (
).
is switched off at the
["GeothHeatAcc." setting - hyst 2°C] temperature
Before selecting geothermal heating for relay 1, make sure that
relay 2 is in a "Not in use" mode and the geothermal heating unit selector switch (start up
/ autom.) is connected to digital input 1 strip connectors 21 - 22.

GeothHeatPart
Temp operated
The regulator controls the relay according to the boiler water temperature (meas. 10).
The relay is activated at the setting (73-75 closed) and the burner starts up. The relay is
released (73-74 closed) and the burner shuts off when the boiler water temperature
reaches the "setting” + "hysteresis” temperature. The function can be selected when
measurement 10 is connected.
The regulator controls relay 1 according to the temperature of measurement 11. The break
before make contact relay is activated at the setting (73-75 closed) and released (73-74
closed) at the end of the set hysteresis (setting - hysteresis). E.g., a cooler's compressor or
an accumulator's charging pump can be controlled with a temperature controlled relay. You
can also adjust the temperature setting for measurement 11 on the user level (see p. 8)
Burner control
When the control mode selected for relay 1 is "GeothHeatPart", the regulator automatically
reserves relay 2 to control the compressor of the geothermal heating and reserves digital
input 1 for geothermal heating selector switch position information (automatic position = strip
connector 21-22 closed). Before selecting geothermal heating for relay 1, make sure that
relay 2 is in a "Not in use" mode and the geothermal heating unit selector switch is
connected to the digital input 1 strip connectors 21 - 22 (start up / autom.).
The regulator
controls the compressor and heating resistor according to the accumulator temperature set
by the user (see p. 8). The regulator also controls the compressor according to the temperature
needed in the heating network. Relay 1 controls the heating resistor.
Heating resistor is switched on at the ["GeothHeatAcc" setting - hysteresis - 3 °C] temperature
(strip connector 73-74 closed). Heating resistor is switched off at the ["GeothHeatAcc." setting -
hyst 2°C] temperature (strip connector 73-74 open). The compressor
and
heating
resistor can be on at the same time. The compressor's and heating resistor's control hysteresis
is set in relay 1's control mode.
