Operating Guide ECL Comfort 210/296/310, application A232 / A332
The application A332.1 is very similar to the application A232.1.
Extras in relation to A232.1:
Return temperature limitation:
The return temperature S10 can be limited, for example not to
be too high (heating) or too low (cooling). If so, the desired flow
temperature at S3 can be adjusted, for example at heating to a
lower value or, at cooling to a higher value.
This results in a gradual closing of the motorized control valve.
In boiler-based heating supply the return temperature should not
be too low (same adjustment procedure as above).
The ON-OFF output X5 can be set to
• follow Schedule 1 or
• follow Schedule 2 or
• follow Schedule 3 or
• switch ON at cooling demand
Alarm A1:
An alarm activates relay 6.
Changes in relation to A332.1:
The ON-OFF output X4 can be set to
• operate as a Humidistat or
• operate as a switch, depending on the outdoor temperature
For a description of the change-over from heating to cooling
operation, please read the section 'A232 in general' .
