EXAMPLES OF DIFFERENT HEATING SYSTEMS:
B) Floor heating
C) Preheating for air conditioning
If the room temperature drops in subzero weather, raise the curve setting at -20 C.
If the room temperature rises in subzero weather, lower the curve setting at -20 C.
If the room temp. feels chilly at zero degree weather, raise the curve setting at 0 C.
In this way you can set the regulating curve to meet the heating needs of your facility.

HOUSES WITH FLOOR HEATING:
Set the EH-201/L regulator's maximum limit b35 ... +40 C and
the minimum limit b20 ... +25 C.
In floor heating solutions it is important to make sure that exessively
hot water which could damage structures or surfaces doesn't ever get
into the network. A mechanical thermostat should be installed on a
supply water pipe which stops the circulation pump in case of
overheating. Ouman Oy keeps CO1A surface mounted thermostats in
stock that are suitable for this purpose. Set the thermostat at
40 ... 45 C.

ATTENTION!
Wait a sufficient amount of time after the adjustment so the change has time to effect
the room temperature.
