EH-201/L has two digital inputs. They can be used either
for receiving alarms, receiving information about exhaust fan running
at ½ speed, receiving a temperature drop command from the home /
away switch, or receiving information about running circulation pump 1
(if pump 1 stops the regulator can be programmed to start a parallel
pump). District heating energy and water meter pulses can also be
connected to digital inputs.
If relay 1 has been reserved for geothermal heating unit control, the
geothermal heating unit selector switch (start up / automatic) is
connected to digital input 1 (strip connector 21-22).
