This simple to use Electric Flow Boiler boost control is designed to provide a manual boost facility for time periods and program settings not covered by the boiler’s Off-Peak supply tariff.In simple terms, when OFF-PEAK energy is not available the control allows on-peak electricity to energize the flow boiler through a manually activated run timer, thus allowing the user to boost their heating throughout the day if required.The Flow Boiler control is supplied with two components – the switching unit (PRE9863FBC-HS) and the push button control (PRE9863 TBC) – normally sited in a convenient remote location. The system will switch boilers up to 12 Kw rating.See Corresponding Data Sheet for wiring instructions.
