Please Note:
This product should only be installed by a qualified electrician or competent heating installer and should be in accordance with the current edition of the IEEE wiring regulations.
2.0 System Overview
Important note: The FH-BU programmer interface is fitted inside the lid of the FH-BU wiring centre, and is used when an FP975-2H programmer is being installed to provide night setback control of an under floor heating system.
Cabling between the FH-BU and the remotely located FP975-2H programmer must be carried out using double insulated cable not exceeding 1mm2 in cross section. The power supply to the FP975 must be run in a separate two-core cable.
The maximum cable length between FH-BU and FP975 must not exceed 10m.
It is important not to run the cable to the FP975 parallel to other mains cables as these may cause interference.
