The controller compares room humidity with the limit values set on operating lines 6137
and 6138 and switches external air dehumidifier K29 connected to an appropriately
defined output QX1 – QX6 (5890 – 5896).
Room temp 10V
The controller receives the room temperature signal in the form of voltage signals (DC
0...10 V). The room temperature in connection with relative room humidity is used to
calculate the dewpoint temperature in the cooling circuit.
If there is no room unit with a room sensor (BSB) connected for heating / cooling circuit
1, the room temperature measured at Hx is also used for room heating / cooling 1
(variant with compensation and room influence).
The respective room temperature is calculated via the linear characteristic which is
defined by 2 fixed points (voltage value 1 / function value 1 and voltage value 2 /
function value 2).
Release swimming pool
This function is to be used to enable direct heating of the swimming pool from
externally via the heat pump and Hx pumps (e.g. with a manual switch).
For direct charging, a release signal is always required at input Hx.
Configuration: Set the function of input Hx to "Release swimming pool" and select the
associated Hx pump at one of the OX outputs.
This function can be used to enable solar heating of the swimming pool from
externally (e.g. with a manual switch) or to define solar charging priority over storage.
Configuration: Set the function of input Hx to "Release swimming pool". For a
description of the function, refer to operating line 2065 "Charging priority solar".

Switch-on command HP stage 1 (heating only)
By closing a contact connected to this input (e.g. by an external controller or a
superposed building automation and control system), stage 1 of the heat pump is put
into operation. It remains in operation until contact Hx opens again or until the heat
pump is shut down by a safety function (e.g. due to high-pressure, low-pressure, or hot-
gas temperature).
Internal requests, DHW requests and requests via bus are suppressed. No
consideration is given to minimum off time and minimum running time. The prerun and
overrun times of the condenser pump and source pump are taken into account. Normal
defrost is possible.
Switch-on command HP stage 2 (heating only)
By closing a contact connected to this input (e.g. by an external controller or a
superposed building automation and control system), stage 2 of the heat pump is put
into operation. It remains in operation until contact Hx opens again or until the heat
