Dimplex Duoheat heaters

[Amp David]

Had a quick look on the way home at a flat with 4 Duoheat heaters.

Theres 2 flexes into the heaters, 1 is wired from a dedicated ring via a FCU next to the heater and the second is via a DP switch which is fed from a radial via a contactor in the CU.

There is also a 10amp switch next to each heater, with 2 browns into com and L1 having a black wire connected to the 4th core of the flex in the FCU next to it. The 2 blues are in a terminal block.

Just having a quick read of the manual for the 4 zone programmer and in mentions a pilot wire system to contol the heaters. Can anyone explain what they mean by a pilot wire please

Heres the programmer

Hi David,
the pilot wire (should be the black) is the means by which a signal is sent from the controller to the 4 Duos.Using the controller you should be able to programme each Duo individually and set the comfort levels you require.
The two supplies are for the normal storage heater function and a radiant front panel facility that backs up your stored heat.
Hope this helps,cheers.

Cheers Pete. Finally got there in the end with the job, As it was they had set it up so that the lounge was on 1 zone and the hall and bedroom on the other zone.

Didn't help as they didn't have an off peak supply connected either
