3 point - controller: (heating-off-cooling function)
Controller output (actuator):
Relay (on/off)
or
bistable voltage output 0/18VDC, 10mA
to drive external solid state relays ( SSRs )
Automatic output control in case of sensor break:
In the event of sensor break the controller automatically
maintains the last valid output ratio as the actuating
output signal.
