3.2.5 Explanations of SERVice parameters
Show software version
The number of the controller's software version is displayed.
Display device status
SERVice parameter 2 is used to read the device status of the EQJW 125. A
value of 0 means that the EQJW 125 is operating without any faults. The
coding for faults is shown in Section 6.1.1. Once the fault has been rectified,
the value for the SERVice parameter is reset automatically.
This coded description of errors is primarily used for fault signalling via bus,
modem or SMS. You can easily read faults directly on the controller in the
ERROR display (Section 6.1).
Software reset
Switching commands and / or SERVice/communication parameters are reset
to the ex-works setting. To do this, the value of the SERVice parameter has
to be changed and confirmed. The EQJW 125 then performs the relevant
reset and assigns value 0 to the parameter.
Manual mode
SERVice parameter P05 is used to disable or enable manual mode. If the
value of the parameter is 0, manual mode is disabled.
Output signal / control model
This parameter is used to select the control signal for the final control
element. You can choose between a signal for 3-point control and a PWM
output (Pulse – Pause) with a fixed period of 64 seconds. If the PWM signal
is used, the signal is available on terminal 4.
When the PWM output is used, the functions for limitation of the flow
temperature are no longer effective.
Room temperature detection
Various types of room temperature sensor can be connected:-
0 = no room temperature detection
1 = connection of room sensor NI1000
2 = Connection for EGS 52/15 or EGT 333 with room sensor
3 = Connection for EGS 52/15 or EGT 333 without room sensor
Using the EGS 52/15 room operating unit, it is possible to change the
controller's operating mode remotely. Moreover, the EDB 100 room operating
unit can be connected via the device bus and can be used to change the
operating mode. The operating mode on the EQJW 125 can also be changed
via a control station using Modbus. In the event of contradictory commands,
the following priorities apply: (i) the settings on the EQJW 125 itself have
priority 1; (ii) the settings via the EDB 100 room operating unit via the device
