to terminal 10, G.

terminal 11, G0.

UO1
Control of heating (FS) or cooling via change-
over.
For 0...10 V DC valve actuator, max 5 mA (FS).
The valve actuator's 0…10 V control signal ter-
minal is connected to terminal 23 and its supply
terminals to terminals 10 and 11. Make sure that
the reference pole G0 is connected to the correct
terminal on the actuator.
alternative
For 24 V AC thermal actuator, max 2.0 A. The
thermal actuator is connected between terminals
23 and 20, GDO.
Using DIP-switch SW8 the output can be set to
NO or NC (see table 3, SW8).
N.B:
when UO1 has been set for use with thermal
actuators for 24 V AC (digital output function) the
controller utilizes time-proportional control to give
a smooth control of the connected actuator. The
output signal for UO1 can be set to NC (normally
closed) or NO (normally open) by changing the
position of DIP-switch SW8. This setting refers
to which type of actuator, NC or NO it is intended
for.
Selection of output function, analogue or digital,
see table 3, SW5.
24
UO2
Control output cooling.
For 0...10 V DC valve actuator, max 5 mA (FS).
The valve actuator's 0…10 V control signal ter-
minal is connected to terminal 24 and its supply
terminals to terminals 10 and 11. Make sure that
the reference pole G0 is connected to the correct
terminal on the actuator.
alternative
For 24 V AC thermal actuator, max 2.0 A. The
thermal actuator is connected between terminals
24 and 20, GDO.
Selection of output function, analogue or digital,
see table 3, SW6.

For external room sensor, PT1000. Range 0...50°C.
Sensor is connected between terminals 30 and 41,
AGnd.
See table 3, SW7.

UI1
For switching between heating and cooling on a
two-pipe system (Change-over).
PT1000-sensor is connected between terminals
31 and 41, AGnd. Range: 0...100°C.
alternative
For potential-free contact. A potential-free contact
is connected between terminals 31 and 41, AGnd.

DI1
Occupancy detector. A potential-free contact is
connected between terminals 32 and 40, +C.
Closed contact corresponds to occupancy.
See also section Occupancy detector below.
33
DI2/CI
The condensation detector S-KG-A/1 (FS). The
sensor is connected between terminals 33 and
41, AGnd.
alternative
Window contact (DI)
A potential-free contact is connected between
terminals 33 and 40, +C. Closed contact indicates
closed window.
See table 3, SW4.

DIP-switches
There are 8 DIP-switches (SW1-8) on the rear of the electronics
cassette, for setting basic functions. Follow tables 2 and 3 below for
setting SW1-8. (FS) in the text indicates factory setting.

Choosing NC
(factory setting) gives direct action on output
UO1, i.e. increasing signal (longer pulses) on increasing
control output.
This setting is used when UO1 is connected to a thermal
actuator of type Argus-ACT-24 (NC). In the event of a power
cut the valve will close.
Choosing NO
gives reverse action on output UO1, i.e. de-
creasing signal (shorter pulses) on increasing control output.
This setting is used when UO1 is connected to a thermal
actuator of type RTAOM-24 (NO). In the event of a power
cut the valve will open.
