Assortment / System Description

58
The universal inputs N.X_ can be configured for use with passive sensors, active
signal sources, and status and pulse signals (see page 28). The analog outputs
N.Y_ and relay outputs N.Q_ are ready configured.
The extension modules RMZ782B and RMZ783B can only be used in connection
with the RMH760B heating controller.
• Weather-compensated flow temperature control of heating circuit
via heating circuit mixing valve, 3-position or DC 0...10 V
• Pump control (system or heating circuit pump)
• Control of DHW heating and storage tank temperature
• Storage tank charging via the common flow, with charging pump or mixing valve
• Storage tank charging via external heat exchanger, with charging pump or
mixing valve

Maximum number of modules: 4 per RMS705B
When using 1 RMZ785, 2 RMZ787 and 1 RMZ788 (maximum 4 modules per
RMS705B), the number of inputs and outputs can be increased, adding …
• 20 universal inputs,
• 2 analog outputs,
• 10 relay outputs: 3 with changeover contact, 7 with NO contact.
The order the different module types are fitted can be freely selected. But the
positions starting from the RM.. control unit must be set.
