AUXILIARY CONTROL
CIRCUIT
AUX Heating Control Loop
The controllers have an auxiliary control circuit for a
second zone
. This control circuit provides an
additional PI control function for applications needing an additional control circuit.
Use the AUX parameters in the settings or the bus to configure this additional control circuit.
To enable it, set “RI1 Mode“ or “RI2 Mode “ parameter to AUX control circuit.
To control the temperature in the second zone, assign the AUX control circuit to an analogue
output (
Y1, Y2, Y3 ). Use the bus (not the display) to control the auxiliary control circuit.
NOTE: RI2 is not available with Type 620 .
The controller has a boost icon (if released),
and it can be linked to priority switching for a configurable boost time.
The boost time (timer) can be configured from 0 to 480 minutes
(0 = permanently enabled, switch off boost using the display or the bus).
The remaining time is shown on the touch display (Fig. 7a).
The following configuration options are possible:
•
Boost disabled
(Disabled)
• Heating stage 1 (Htg Stage 1)
• Heating stage 1 + heating stage 2 (Htg Stages 1&2)
• Cooling stage 1 (Clg Stage 1)
• Cooling stage 1 + cooling stage 2 (Clg Stages 1&2)
• Humidification control circuit (Humidification)
• De-humidification control circuit (De-Humidification)
• CO2 control circuit (CO2)
•
Fan
• Aux control circuit (Aux. Loop)
Digital input boost (without timer)
If the digital input for boost mode was configured,
you
cannot exit the mode on the display and it remains
active until the input status changes.
Digital input boost is shown with an icon and the text “ Boost ”
(instead of the setpoint) in the large circle (Fig. 7b).
