An X in the pump table doesn’t necessarily mean that the corresponding installation cannot be built.
If it can, it will need specific design effort and pump selection. Please consult EHS for advice.

UMP CONTROL
The applied pump must be controlled only by the CD
+
water heater control. If, for any reason, an
external pump control is applied
without written approval of EHS
, then the complete warranty on the
CD
+
water heater and all delivered parts will become invalid.

:
MAXIMUM ELECTRICAL POWER
General
- The inrush current of a conventional pump is approximately 2½ x its nominal current.
- The maximum switch current of the relay on the PCB is 5 A.
The conclusion from this is that nominal currents of pumps, controlled by the PCB, may not exceed 2 A.

pump.
The nominal current of the pump must be equal to or lower than 2 A.
All pumps of § 9.7.1 fulfil this condition.
Warning (EC pumps):
In case of using an electronic commutating pump, the relays 1, 2 or 3 may not be used for the power connection,
because of the inrush current of the electronics of the pump.
Directly connect the pump to an external power supply.
Control connections of an EC pump can be established in several ways, set by parameter P5BN.
See § 11.1.5 on page 85.
