Actuator (SDM24)
Dimensions and technical specifications
Application
The actuator (SDM24) is modulated and gives
the correct heat. SIRe can be set to always
allow a small leakage flow through. This is
to provide quick heat supply when a door is
opened but also to provide a degree of frost
protection.

Operating status indication
Function
Actuator is controlled by a 0-10 V signal.
The valve is open in unaffected position.
The actuator should be in "Reverse Action,"
dipswitch no. 4 should be set to ON, which
means that at 10 V, the valve is unaffected,
ie fully open for heat input. In the closed
position SIRe still gives an output of 0.5 V to
pass through a small leak flow through the
valve.
The actuator is self-calibrating and sets the
end positions by itself.
Dipswitch settings
SDM24 is adjustable, this is done by setting
dipswitches. These are located under the
actuator cover. To SDM24 to work with SIRe,
dip no. 4 should be set to = ON as follows, i.e.
"Reverse Action":
OFF No power supply
