7.8 Connection Chart
Note that the volt free contacts are not fused. If these are used to power
any external equipment, the installer must provide adequate fusing or other
protections.
These contacts are rated at 3A resistive, 0.5A inductive.
Fault connections - No fault = the relay is powered.
Fault = the relay is unpowered.
Heat demand - the relay is powered when heating is selected.
Cool demand - the relay is powered when cooling is selected.
A fan start delay can be imposed to allow the damper time to open. This is
adjustable via display screens or commissioning tools.
If an I/O damper is fitted, it must be wired to the fan run relay, and the relay
supplied with the relevant supply voltage.
If required the damper end point relay can be connected in series with alarm
circuit 2 to monitor for damper faults. The multi-state value ‘IO Damper Fitted’
must be set to yes. This will allow the system to ignore alarm circuit 2 if the fans
are not running and dampers are closed.
See I/O Damper connection diagram for details.
Switch Live (SL) terminal - A signal of 100-230V a.c. will activate the switched
live signal.
Switch Live 2 (SL2) terminal - A signal of 100-230V a.c. will activate the
switched live 2 (Fan Boost) signal.
Note that a signal from an isolating transformer will produce an unpredictable
result and is not recommended.
Extra low voltage versions of the switched live signals are also available. Link two
contacts to activate the signal.
