Figure 31 Installer’s Digital Input Connections (AS03)
A link wire should be placed between the terminals for the ‘Master On/Off’ and also between
terminals for the ‘Mode Heat/Cool’ function and ‘Over heat Protection’. This will ensure the unit
is on and set in heating mode. Volt-free connections can then be made to the ‘DHW On/Off’ and
‘Heat/Cool On/Off’ from a remote source such as a timeclock, programmer or room stat.
Connecting the terminals for ‘DHW On/Off’ (5 & 6) will set the unit into DHW mode. Connecting
the terminals for ‘Heat/Cool On/Off’ (7 & 8) will set the unit into heating mode (provided the link
wire is connected between the ‘Mode Heat/Cool’ terminals.
NOTE: Connections are volt-free, no voltage should be connected into any of them.
Connecting any kind of voltage to the terminals will damage the control board inside the
unit.
3.10.3 Temperature Sensors
There is one additional temperature sensor which needs to be connected to the unit in order to
achieve full functionality. This sensor is a DHW storage temperature sensor. The sensor is
supplied with the unit but the wiring to it may need to be extended. The wires should be ran
separately to any power transmission cables, however, if they need to run close to or in the same
conduit as power transmission cables, then shielded cable should be used. The type of
temperature sensor to be used is NTC 10kΩ.
The DHW storage temperature sensor is used to control the DHW heating requirements. It must
be connected or this will cause a fault and trigger an alarm. The unit will arrive with a link wire
complete with a built-in resistor in order to give a reading and enable the unit to operate. The link
wire which is wired into the ‘TT’ (11 & 12) terminals of the installer’s wiring enclosure needs to be
removed and replaced with the supplied DHW storage temperature sensor. The sensor should
be located in a stat pocket on the DHW storage cylinder to give an accurate indication of the
cylinder’s temperature. If the unit is only to be used for space heating, the link wire complete with
resistor should not be removed from the ‘TT’ terminals.
