Use
The RWB1007 electronic timeswitch is designed to control combination boilers and single zone
applications together with the appropriate thermostat.
Functions
Service interval reminder function
The boiler service interval reminder function complies with Regulation 36 of the Gas Safety
(Installation and Use) Regulations 1998, requiring landlords to carry out a safety check at
intervals of no more than 12 months.
If the function is enabled, a message is displayed on screen, informing you about the number of
days remaining until the next boiler service is due, up to 50 days prior to the actual service date
(the prewarning period is set by the engineer, default is 50 days). Normal functions continue
during this stage.
The amount of prewarning days has to be entered by the installer, maintenance engineer, or
the landlord. Contact them when you see the warning for the first time. From then, the display
will switch between the normal display and the amount of remaining days. The RWB will also
emit a 5-second sound hourly between 09:00 and 21:00.
If the RWB goes past the service day, the system will be switched off with only the one-hour
“boost” feature working, and the display will switch between the real time and OFF.
Mechanical design
The unit consists of the following parts:
● Plastic housing with electronics (inputs, outputs), operating elements (HMI) and DIP
switches
● An industry standard backplate with screws
