3.14.6 External Inputs

There are two external inputs for direct control
of the operating mode of the system.
The ON input forces the controller to operate in
the on mode for as long as the input is active
(switch closed). This could be used for an
override on switch or for BMS control.
Note: If the controller is to be used in a BMS
system then all of the ON times should be set
as unused, then the controller will by default
control at off/night temperature. The BMS
system can then activate on/day or frost
temperature control using the external inputs.
EXTERNAL / BMS
AUTO
The FROST input forces the controller to
operate in the frost mode for as long as the
input is active (switch closed). This could be
used as a holiday switch or an off switch or as a
door interlock to turn the heating off when a
door is open or for BMS control.
EXTERNAL / DOOR
FROST ONLY
In addition the remote Frost input can be
assigned under engineers menu to act as a
multipurpose alarm input, blocked filter alarm
input or an air flow failure alarm input with
contacts closed for fault condition, open for
good condition.
In blocked filter mode the control will display the
following warning with the time and operation
continuing as normal.
ARN I NG !
BLOCKED F LTER
NB. The controller will ignore the input for the
first 30 seconds
In air flow failure mode the control will display
the following warning with heating operation
suspended until a lockout reset operation is
performed.
O F
I
18
ARN I NG !
I
A RFLO LOCKOUT
NB. The controller will ignore the input for the
first 30 seconds.
As a multipurpose alarm the control will display
"REMOTE OFF - CHECK" and the heating
operation will be suspended until the fault is
corrected.
ARN I NG !
REMOTE OFF - CHECK
NB. The controller will ignore the input for the
first 30 seconds
Further in a multi-zone system air flow failure on
a slave will be displayed on the Master as a
lockout with the zone number and lockout reset
can be achieved either locally on the affected
slave or centrally using the Master controller.
As a multipurpose alarm the input will be
effective at all times, whereas in air flow failure
and blocked filter modes the controller will ignore
the input until 30 seconds from the start of either
the heat or time relays as set under the
engineers menu.
In a multi-zone system the external inputs to the
Master controller will be applied to all zones
automatically, however individual zones can be
set to ignore the FROST signal from the Master
under the engineers menu. The external inputs
to a slave controller will apply to that zone only.
3.14.6.1 Priority order of controlling
items.
If ON and FROST inputs are both active then the
FROST input will take priority.
Where more than one input or setting is trying to
operate the control it will respond to inputs in the
following priority order:
1. Remote Frost input
2. Overtime (operating with NORMAL/HEAT
ONLY/VENT ONLY)
3. Vent mode
4. Holiday
5. Off mode
6. Frost Only
7. Remote On (BMS) input (operating with
NORMAL/HEAT ONLY/VENT ONLY)
8. Time program (operating with AUTO/
HEAT ONLY/VENT ONLY)
