Assortment / System Description

47
The RMK770 boiler sequence controller is supplied with 18 plant types. They
represent combinations of heating plants.
To ensure optimum plant operation, the various plant types are configured with
boiler sensor, main flow sensor and main return sensor.
The 6 hydraulic circuit types K1.x through K6.x form the plant type basis in the
boiler sequence controller. Each type of hydraulic circuit has 2 boilers; extensions
up to 6 boilers are possible.

3132S16
Multiboiler plant with:
- 1 pump in the return of each boiler
- 1 shutoff valve in the return of each boiler
Multiboiler plant with:
- 1 pump in the return of each boiler
- Maintained return temperature of each boiler
with mixing valve (modulating or 3-position)
The type of burner can be selected for every type of hydraulic circuit:
• K_.1 1-stage burner, optionally modulating burner (DC 0…10 V)
• K_.2 2-stage burner
• K_.3 Modulating burner with 3-position control
The 6 hydraulic circuit types K1.x through K6.x and the 3 selectable burners K_.1
through K_.3 produce the 18 plant types K1.1, K1.2, K1.3, K2.1, ..., K6.3.
