UNIT WITH A WATER COIL
On units with a water coil the supply air temperature is adjusted using
the thermostat valve in the unit, see the figure below.
The table under the figure shows the temperature corresponding to the
set value. We recommend settings 3 or 4 in heating mode.
In summer we recommend *.

The frost monitor is used to prevent frost damage to the water coil
when outdoor temperatures are low. The frost protection sensor on the
water coil return line generates an A alarm that stops the unit when the
water temperature drops below 10 °C. Investigate why frost protection
tripped and then reset the alarm.
