To connect external inputs for zone control via thermostats (B19/B20/B21/B22/B23/B24)
• Make sure to wire the thermostats for the zone control to the correct terminals (zone1/ zone2, cooling / heating).
• Make sure the external thermostat is rated for 220-240V~ input.
• The input signal is a switched Live (L). Zone2 has a priority over Zone1. The mode of operation (cooling or heating) will
be determined by Zone2 (when two signals are simultaneously applied).
