Brief description
• RC35 programming unit, combined with a WM10 low
loss header module and two MM10 mixer modules, one
heating circuit without control and one with mixer, plus
cylinder primary and DHW circulation pump.
• Time-dependent actuation of the DHW circulation
pump and cylinder primary pump possible via the
RC35 programming unit.
• The RC35 programming unit can be installed either
inside the gas condensing boiler or in a reference
room.
• Optional DHW heating in parallel mode.
• Up to three heating circuits with mixer and one heating
circuit without mixer are feasible with the RC35
programming unit.

• An individual time channel is available for DHW.
Special design information
• For the Logamax plus GB162-65/80/100 two modules
may also be installed inside the appliance.
• In combination with a low loss header, the integral
pump in the pump connection assembly of the GB162
must be controlled subject to output (setting 0 at the
RC35 programming unit).
• For the Logamax plus GB162-65/80/100, order the
pump assembly as an accessory.
