Electrical Connection Of A Controller - Promatic WDC10B Manual

ELECTRICAL CONNECTION OF THE CONTROLLER
Every heating controller project must be based on calculations and plans that
are exclusively your own and pursuant to the regulations in force. Images and
texts in these manuals serve as examples and the issuer does not assume
any responsibility for them. Issuer liability for unprofessional, false or incorrect
information or consequential damage is explicitly excluded. We reserve the
right to technical errors or changes without giving prior notice.
Installation of controller devices shall be done by a qualified technician or an authorised or-
ganisation. Prior to any intervention into the wiring, make sure that the main switch is
switched off. Low voltage installation regulations IEC 60364 and VDE 0100, statutory provi-
sions for accident prevention, statutory provisions for environmental protection and other
national rules shall be observed.
Before you open the housing, make sure that all poles of electrical supply had been discon-
nected. Failure to follow these instructions can lead to serious injuries, such as burns or
even threat to human life.
The controller must be connected via switch connector for all poles. Pole space with switch
open shall be at least 3 mm.
All low voltage connections, such as connections of temperature sensors, must be placed
separately from connections under power. All temperature sensor connections shall be
placed into the left field and all connections under power shall be placed in the right field of
the controller. Output R6 is by models WDC10 and WDC20 a semiconductor relay and is
intended for pump speed control.
