Hi, I am looking for a solution to be able to programme heater switch of / off times on a continuous basis. My current Multicontrol for a Thermo Pro 90 heater on a boat is programmable for 7 days, but after 7 days the timers must be re-activated. Is there a solution for a continuous timer, perhaps with a different control unit? The idea is to be able to leave the boat more or less unattended for a couple of weeks during winter and have the heater switching on at times to prevent frost damage.

Hi Daniel. The ideal solution for continuous repeat timer programming of your Thermo Pro 90 heater is the Webasto 7 Day Marine Timer found at https://www.butlertechnik.com/item/Webasto/7-Day-Marine-Timer-Programmer-Thermo-Top-12v-Heater-4110551A/57G. You must have a 12v heater for this controller. Regards Michael.

Hi, thanks, so this timer runs continuously then?

Yes this timer works continuously without having to reset it every 7 days. It cannot be used to regulate the temperature of your Webasto water heater. The heater is designed to maintain a consistent coolant temperature. Components such as radiators and blower boxes should have their own thermostats.
