KOB Pyrot Installation & Operation

Parallel heat generator control [Art.-No.: ECO-KP0]
The additional heat generator designed as a hydraulic switch supplies heat to the storage unit either
separately or in conjunction with the biomass boiler. It is controlled in such a way that the additional
heat generator covers the required peak and the biomass boiler covers the basic requirements
taking account of the biomass boiler’s delayed response. The boiler pump is active and the motor
shut-off device is open during the additional heat generator’s operating phase.
Included in the delivery:
- Button for additional heat generator
- Boiler pump contactor and motor protection device (additional heat generator)
- Control output for pump (1), mixing valve (2) and burner (3)
Attention: Only for PYROMAT-DYN without ECO function and PYROT with hydraulic switch.
See Hydraulic Drawing 3950 PYROMAT-ECO or 6960 PYROMAT-DYN with ECO function
Controller for Heat Generator, parallel [Art. No. ECO-KP1]
When required, an additional heat generator is automatically connected. This may occur
after heat is taken from the accumulator to cover the overall heat requirement (stand-
alone operation). Or the additional heat generator may be used to cover a peak
requirement for heat (parallel operation to the PYROMAT). For parallel operation, a
burner group is necessary for heat diversion, which simultaneously also provides for
keeping up the return flow. On request, the additional heat generator can load the
accumulator (as desired to B28.1, B28.2 or B28.3).
Includes:
- Pushbuttons for additional heat generators
- Controller output for pump (1), mixing valve (2) and burner (3)
- Return flow sensor QAD 21, uninstalled
