Heating Heating
Mode Select the Mode of control that best
suits the occupation pattern and use
of the building Night Setback
– Uses a compensated curve for
Day and a reduced heating curve for night
periods. Typically used in 24hr occupied facilities.
Typically used when replacing older controllers
like CSC with time clock. Also used automatically
if the Room Sensor reading is not available when
in the Opt/Comp mode.
Opt/Comp
– Optimised compensation typically
used in part occupied buildings such as schools or
offices. Used when replacing older products like
CSMC/DC1100/DC1400CMC/RVL45/Aquatrol
Timed On/Off
– Used when optimisation is not
possible/required and night setback is not
required. Can be used when replacing older
controllers like Satchwell CSC
Optimiser
– Used to start/Stop external systems
based on heat up rates and cool down rates.
Typically used when replacing older products like
Satchwell SVT
Opt YPLAN Mode
–
Configure the controller to
replace older Y Plan systems. Optimise the
heating and allow more energy saving by
compensating the boiler when the HWS is
satisfied.
VT Set point The controller can adjust the heating
curve between the min and max limits
configured based on the room
conditions. This is otherwise known
as Room Influence. Non-Adaptive (Default)
Self-Adaptive
Optimum Off You can allow the controller to turn the
heating off early subject to the time
schedule, space temperature and
cooling down rate of the building
being aligned. Sometimes Optimum
off is not required due to fan heaters
or AHU being on the same pipe circuit. Enabled (Default)
Disabled
HWS Priority If the boilers are linked to the HWS
and the HWS Control option is
selected you can allow the HWS to
have priority over the heating system
given certain conditions or site
limitations. The method of gaining
priority is either to close the VT Valve
for a period of time or to turn the
heating pump off for a set period. E.g.
Can be used when boilers struggle to
heat all services at the same time. No Priority (Default)
On Valve
On Pump
