5) By-pass control
According to inside and outside temperatures, the TAC4 DM control will monitor the opening/closing of the
bypass damper. A servo-motor (SMO) will have to be installed (option).
Operating description:
Opening of by-pass(*) if all following conditions are met:
- Outside T° (sensor T1) < inside T° (sensor T2) – 1°C.
- Outside T° (sensor T1) > 15°C.
- Inside T° (sensor T2) > 22°C.
Closing of by-pass if one of the following conditions is met:
-
Outside T° (sensor T1) > inside T° (sensor T2).
-
Outside T° (sensor T1) < 14°C.
-
Inside T° (sensor T2) < 20°C.
All these temperature SET values can be modified using ADVANCED SETUP (see
