EXAMPLES OF DIFFERENT HEATING SYSTEMS:

) Floor heating
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 203GT 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.
