Daikin EKOMB22AAV1 [17/60] Underfloor heating distributor without pump

Daikin Europe NV

Underfloor heating distributor without pump

Connect the underfloor heating system (D) and set the maximum CH supply temperature of

the boiler to the design condition. Fit a clamp thermostat (A) onto the supply tube

underneath the boiler. The clamp thermostat with blind cap must be set to a maximum

supply temperature of 55°C.

Assemble the on/off room thermostat (B) and connect it in series with the clamp thermostat

to connector X4 - 6/7 in the unit. See par. 10.1.

In this situation, the pump in the boiler is used to bridge the loss of pressure of the

underfloor heating system. Using the loss of pressure graph par. 7.4, the maximum loss of

pressure of the underfloor heating system can be determined.

Make sure there is a minimal water circulation. See par. 7.3. If required, install a by-

pass valve (C).

In case of an underfloor heating system without pump, we recommend changing the

following parameter settings:

par. o from 0 to 3.

par. P from 5 to 2.

Parameter 3 must also be set to its minimum level, or the

transmission loss of the property.
