9.10 TMC CONDENSER PRESSURE REGULATOR (ACCESSORY)
As accessories, speed regulation systems are available, installed inside the unit, for the remote condenser fans. Two dierent
types of regulation are available, depending on what type of condenser is used.
9.10.1 ELECTRONIC CUT-OFF (AC) FAN SPEED REGULATORS
Electronic cut-o speed regulators are normally used to proportionally and continuously vary the speed of condensers with
AC fans, with 230 Vac power supply, suitable for cut-o control.
These work with simple voltage variators, whose control signal is supplied by the unit’s SySmart regulator through a 0-10
Vdc signal.
They are controlled by specic SySmart regulator parameters, accordingly you need to refer to the relative user manual for
their adjustment.

electronic fans, or condensers with built-in control.
The 0-10 Vdc control signal is sent by the unit’s SySmart regulator.
