8.10. Layout Outputs
Max. output load:
- Triacs (connections 10 -12): max. 3.15 A
(max. 2A per Triac)
- Relays (terminals 20 -37): max. 6.3 A
8.10.1. Analogue Outputs (80-87)
The sensor inputs on the central unit are described in
the electrical wiring.
8.10.2. Triac outputs (10-12)
The sensor inputs on the central unit are described in
the electrical wiring.
8.10.3. Digital outputs 230V AC (20 -38):
Bei HGL-Wärmepumpen wird die Klemme 36-37 zur
Ansteuerung der Zirkulationspumpe verwendet!
Bei Basic-Wärmepumpen erfolgt über die Klemme
36-37 die Umschaltung zwischen Heizung und Vor-
rangladung!
Die Belegung der digitalen Eingänge auf der Zent-
raleinheit ist aus dem für die Anlage zugehörigen
Elektroschaltplan zu entnehmen.
8.10.4. Connection of the mixers
The ESBE mixers are connected as three-pole
according to the wiring diagram enclosed.
Mixer open = brown
Mixer closed=black
8.11. System Ear thing
When the protective conductor is connected correctly,
the electrical panel and the heat pump casing are
earthed.
After maintenance work, ensure that the equipotential
bonding is properly re-established.
8.12. Maximum Restriction for Under floor
Heating
With underfl oor heating circuits, an additional clip-on
thermostat must be fi tted and the relevant heating
circuit pump supply switched via it in series.
8.13. Composite signal zone valves
The composite signal zone valve setting generates
a request when one of the zone valves is open. The
difference to a roomstat function is that, indepen-
dently of heating or cooling operations, a request is
generated when a zone valve contact is closed.

eating circuit A
If you are using zone valves, you can
generate composite signal from all zone
valves to be able to switch the heating
and cooling circuit on and off with the
thermostat function.
