Building Technologies Boiler sequence controller RMK770 CE1P3132en
HVAC Products 3 Commissioning 23.04.2009
Common plant components (main pump, system pump, primary controller) must also
be connected to the controller with the boiler master.
If in total more than two boilers are in operation, the number of boilers must be set on
the boiler master.

Communication between the 2 RMK770 takes place via KNX bus. It must be activated
via the Communication menu. For more detailed information, refer to chapter 14
“Communication”.
3.6 Wiring test
A wiring test can be made with all connected peripheral devices. On completion of the
configuration and after having made all settings, it is recommended to conduct this test.
At the inputs, the current states or values are displayed.
The aggregates (pumps, actuators, etc.) connected to the outputs can be switched.
In the case of modulating outputs, a signal can be delivered in the relevant value range.
The application is deactivated during the wiring test. The outputs are in a defined OFF
state; safety-related functions are deactivated.
In the wiring test, the inputs and outputs are to be checked for the following faults:
• Wiring error, that is, wires have been mixed up
• Position fault, that is, wires of sensor or actuator have been mixed up
• Discrepancy between actual type of connection and controller configuration (e.g.
LG-Ni1000 in place of DC 0…10 V)
