Firmware V1.40 - Doku 2.1 06. April 2016
4.2.2.7 Forced actuation (bypass interval)
Controller type: UA 111 XP
In certain operating states it may happen that the pressure switch does not demand any additional compressor
over an extended period although the refrigeration point requires additional refrigeration output. Accordingly, a
time interval can be defined in minutes for forced actuation, after which the controller will load a compressor re
gardless of none being demanded by the pressure switch.
This interval is reset every time a cooling relay is energized. Actuation takes place for the duration of the bypass
interval set in seconds. After that time, control of the compressors is restored to the pressure switch.
4.2.2.8 On-off control by all supply air sensors
Controller type: UA 111 X and UA 111 XP
Control takes place through all connected first-zone supply air temperature sensors.
Single-zone operation:
In single-zone operation, cooling relay 1 and the compressor outputs are actuated.
R2.1 .. R2.8:
Supply air sensor
(Terminal Z11/12; Terminal Z31/32 .. Terminal Z91/92)
R4.1:
Return air sensor
(Terminal Z21/22)
Valve 1:
Solenoid Valve 1 relay
(Terminal 25/26/28)
Compressor 1 relay
(Terminal 43/44)
Compressor 2 relay
(Terminal 53/54)
Compressor 3 relay
(Terminal 63/64 - UA 111 XP ONLY)
When connecting the supply air sensors, make sure there are no free locations between the con
nected sensors. For example, when connecting four supply air sensors, the consecutive inputs R2.1
to R2.4 must be used.
