KOB Pyrot Installation & Operation

Controller for Air Handling Unit Group [Art. No. ECO-L]
The burner storage system supplies the air heaters with maximum flow temperature. The fans are
switched by switches or controllers provided by the customer. The flow rate for the heating water is
controlled by the return flow temperature and so adjusted to the heat output of the air heater
(quantity control). This produces optimum storage stratification for a long time and at a high
temperature at the accumulator flow pipe. An integrated timer can be used to set the heating
periods (daily and weekly schedules).
Includes:
- Pushbutton for air handling unit group
- Controller output for pump (1) and mixing valve (2)
- Return flow sensor QAD 21, uninstalled
- Baffle bypass
Controller for Domestic Water Heater [Art. No. ECO-B1]
When the temperature of the domestic water drops, it is reheated by the built-in heat exchanger
either from the burner or from the heat accumulator. A prerequisite for this is the temperature
difference required (choice of control either according to temperature difference or fixed
temperature).
An integrated timer can be used to set the heating periods (daily and weekly schedules).
Includes:
- Pushbutton for domestic water heater
- Controller output for pump (1) and shut-off valve (2)
- Domestic water sensor QAZ 21.5220 with dipping shell, ½" x 200 mm, uninstalled

Controller for Domestic Water Circulation System [Art. No. ECO-BZ]
An integrated timer can be used to set the circulation periods (daily and weekly schedules).
The duration for the circulation pump to be switched on can be adjusted using a cyclical switching
system.
Includes:
- Pushbutton for circulation system
- Controller output for pump (1)
