Installation and maintenance instructions

ROTEX HPSU compact Ultra RHSX(B)-D

Heat pump (indoor unit) with integrated heat accumulator

008.1444444_01 – 11/2018 – EN

For heating support or as an alternative to an electric backup heater,

an external heat generator (e.g. gas- or oil-fired boiler) can be con-

nected to the indoor unit. To connect an external heat generator, the

connection set for external heat generators must be installed (see

Chap. 4.5).

The heat supplied by the external heat generator must be fed to the

unpressurised storage tank water in the hot water storage tank of the

indoor unit.

▪ Implement the hydraulic connection according to one of the two

following options:

▪ unpressurised via the connections (solar inflow and solar

return flow) of the hot water storage tank

▪ for …Biv indoor unit device types, via the integrated pres-

surised solar heat exchanger.

▪ Comply with the instructions on hydraulic connections

(seeChap. 1.2)

▪ Examples of the hydraulic connection (seeChap. 6).

The external heat generator request is connected via a relay on prin-

ted circuit board RTX-EHS (see Fig. 4-38). Electrical connection to

the indoor unit is possible as follows;

▪ External heat generator has a potential-free switching contact con-

nection for heat request:

▪ Connection to K3 if the external heat generator is responsible

for the domestic hot water preparation and the backup heating

(setting of the [Config. of external heat source] parameter =

DHW + heating support [→Main menu →Settings →Ext.

source])

▪ Connection to K1 and K3 if two external heat generators are

used (setting of the [Config. of external heat source] parameter

= Two external heat generators [→Main menu →Settings

→Ext. source])). In this case, K1 connects the external heat

generator (e.g. gas-fired or oil-fired boiler) for heating support

and K3 connects the external heat generator (BUxx) for do-

mestic hot water preparation.

▪ Connection to AUX connection A (seeChap. 4.7.13)

▪ External heat generator can only be connected via mains voltage:

Connection (~230V, maximum load 3000W) to K1 and K3.

CAUTION

Danger of voltage flash-overs.

▪ The connections of the RTX-EHS printed circuit board

must not be used simultaneously for connecting mains

voltage (~230V) and SELV ("Safety Extra Low

Voltage").

1 Refer to the external heat generator's respective installation in-

structions for a suitable electrical connection.

2 Installing the connection set for external heat generators (see

Chap. 4.5).

3 Make suitable connections on the RTX-EHS printed circuit board

of the connection set (see Fig. 4-38).

4 Fix cables that are fed into the connection set from the outside

using the strain relief clips and cable ties included (see steps 7

and 8 in Chap. 4.7.4).
