The desired room temperature must be set at the room thermostat. Simi-
larly, the room thermostat with timer should also be properly set. It should be
understood that the room thermostat with timer allows only one lower room
temperature level, which then will be activated by the timer. There will be no
corresponding decrease in the feed line temperature.
Instructions for the operation of the room thermostat with timer should be
taken from the manual provided with the unit.
The desired constant temperature for the feed line water, with which the
heating system will be heated until the room temperature has been reached,
must be set at the setting knob K.
The heating surfaces then will be heated with the preset constant tem-
perature until the preset room temperature has been reached. The heating
elements will then be turned off.
It is important that the set constant temperature is always lower than the
maximum permissible feed temperature. This is especially important for floor
heating applications.
