THERMOSTAT WIRING

The Audax interface board has two connectors marked TH1 and TH2 which may be used to control the Audax using a ther-
mostat, chronostat, programmer or switch.
Each of these terminals has four pins, three of which provide L, N, E, and a switched input. Applying 230V to the switched
input will activate the zone valve and turn on the audax.
Here follows three example wiring diagrams. Read and refer to the specific manufacturer's instructions for the type of
thermostat, chronostat, programmer, switch or other device used, prior to installation.

4.3.1 CONTROL USING 230V MECHANICAL THERMOSTATS

A mechanical thermostat may be used to switch 230V from the L pin of the TH1 or TH2 terminal to the SW pin.

4.3.2 CONTROL USING 230V DIGITAL OR DIGITAL PROGRAMMABLE THERMOSTATS

Where the external device requires 230V to operate, provide Live Neutral and Earth from either TH1 or TH2. The live should
be looped through the switched contact back to the SW pin on the TH1 or TH2 terminal.
