Connecting The Outside Sensor; Centralised Load Control And Load Monitor - Nibe FIGHTER 310P Installation And Maintenance Instruction

Install the outside sensor (15) in shade on a wall fac-
ing north or north-west, so it is unaffected by the morn-
ing sun. The sensor is connected with two-wire cable
to terminal (14) positions "7" and "8".
If a conduit is used it must be sealed to prevent con-
densation in the sensor capsule.
Sluttekontaktfunksjon
The output steps of the immersion heater can be dis-

connected by means of a load sensor or a centralised
load control relay. This can be done either with floating

make or break contacts, connected to terminal block

RS
(14). The required contact function is chosen with a
jumper on the PCB (34) behind the front panel (see
RS
BV
below). The heat pump is delivered with a strap on pins
5 and 6, which gives a make (NO) contact function.

not cause power disabling.

For break (NC) contact function, move the strap to pins

If both a load sensor and centralised load control are
to be used, the contact functions must be the same for
both (both make or both break). The contacts must be
connected in parallel for make contact function and in
series for break contact function.
