XBOXER XBC ECOSMART ADAPT (TREND) CONTROL (AT)

15.0 Electrical Details

The electrical wiring must be carried out
by competent persons, in accordance with
good industry practice and should
conform to all governing and statutory
bodies i.e. IEE, CIBSE etc.
15.1 Volt Free Contacts
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 5A resistive, 0.5A inductive.
Run connections - The relay is powered when the fan is running. (These
contacts are used when an I/O damper is installed. See damper section 5.2 for
details)
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.
15.2 Switched Live
Switch Live (SL) terminal - A signal of 100-230V a.c. will activate the switched
live signal.
Switch Live 2 Boost (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.
Volt free versions of the switched live signals are also available at terminals
T33-T34 & T35-T36. Link two contacts to activate the signal.
15.3 Damper Connections
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. See I/O Damper connection diagram
for details.
