Safety instructions
Only authorised electricians are permitted to work on a 230 V mains voltage. The safety regulations
of the VDE and the local electrical utility company must be observed
The connection work stated in these instructions must not be carried out when the mains voltage is
switched on.
A 30 mA residual current circuit-breaker must be used in humid areas (such as bathrooms) in
accordance with VDE 0100.
The mains supply must be protected by means of a miniature circuit-breaker (16 A).
A terminal cross-section of 2.5 mm
2
must be used for a heating output of 3 kW or higher.
Description/application range
The electronic temperature controller with timer control is designed for controlling the floor
temperature and/or the room temperature in individual rooms.
It can be used, for example, for electrical direct heating (floor or convectors), supplementary heating
for floor background heating in bathrooms, electrical perimeter heating or warm water heating with
control valves. The controlled variable is either the room temperature using an integrated room
temperature sensor or the floor temperature using the supplied floor temperature sensor at the level
of the heating mat.
AC 230V
normally closed
control valves are used for the control of warm water heating systems.
