Starting of operation without given values
1. Remove protection cap / or thermostatic head / or electric drive from
the MOH1 (see page 8 picture 1).
. Increase the supply temperature from the radiator-/boiler circuit to the
designed value (normally 131-140°F).
3. To perform the adjustment check, the room temperature has to be
at least 68°F. If it is not, the system has to be run until the temperature
increases.
4. Check the floor heating supply temperature. It should be about
95-104°F. If it is too high, the flow from the primary supply has to be
adjusted (reduced), see page 8 picture 3.
The MOH1 will be delivered from factory with fully opened mixing
valve. We recommend an adjustment in small steps (1/ turn). After
each adjustment the floor heating supply temperature should be
checked after an appropriate waiting period.
