Compatibility
The C1727 Smart Programmer is compatible with most heating control systems and is ideal
for S and Y plan system boilers using spring return valves.
It works well with compatible combination or system boilers as well as heat pumps
requiring On/O control. Shipped with a standard 6-pin back plate, it can easily replace
Centaurplus and Serviceplus time switches and programmers requiring minimum of wiring
changes.
