OPERATING MODES
The Digistat can be operated in one of three modes.
1) – Timed, all preset times and temperatures
2) – Continuous night temperature (useful for low limit temperature
protection when on holiday)
3) – Continuous ‘DAY 1’ temperature
Use the SELECT button to change the operating mode to suit your
requirements, the symbols are positioned on the right hand side of the display.
TEMPERATURE OVERRIDE
If at anytime during normal operation, you wish to temporarily increase or
decrease the set temperature use the + or – buttons to change to your
desired setting. This can be done without entering the SET mode. 5 seconds
after releasing the + or – button the display will revert to showing the actual
room temperature. The Digistat will now control the temperature to the
override setting until the next programmed switching time, when it will revert
to the times and temperatures you have already programmed.
The Digistat RF3i features unique self learning optimum start software.They can
help achieve savings in excess of 10% on heating costs and reduce CO
2
emissions,
by delaying the start time on milder days without affecting your comfort level.
USER INSTRUCTIONS FOR OPTIMUM START
There is no extra programming involved. The self learning software is factory
preset and will start to monitor and adjust the heating start times for setting ,
as soon as the unit is installed.
The optimum start feature only operates on the first switching time of each
day ( ). Switching times , and switch at the programmed times
without any delay.
The delay period can vary between 0 - 60 minutes depending on:
a) The actual room temperature at the first switching time ( ).
b) The set temperature of the Digistat RF3i.
c) The stored data on how fast the heating system responded the previous day.
During normal operation the flame symbol on the display indicates the
current operating status.
Flame on = heating on
No flame = heating off
FIashing flame = saving energy (optimum start cycle operating)
When the flame is flashing, the optimum start cycle can be overriden by pressing
the + button once.This returns the unit to normal operation.
IMPORTANT
Always set your heating to the time that you would normally wish it to start
allowing for the coldest weather conditions. Optimum start will automatically
delay the start time and save you money on milder days.
DIGISTAT RF3i
Once the ‘wireless system’ has been commissioned,
the unit will display the actual room temperature
and the time at somewhere after 12.00 midnight
(Diagram A).
Note: If this unit has replaced a standard room
thermo-stat and/or a programmer is incorporated in
the control system, it is suggested that the central
heating (CH) channel is switched to On/Cont/24hrs.
Operation of the heating times and tempera-tures
will be controlled by this unit.
Diagram A Diagram B
Digistat RF3i has an indicator to show when the heating system is ON or OFF,
e.g. if the SET temperature is 20°C and the actual room temperature is below
20°C a flame symbol will appear on the display (Diagram B). This indicates a
demand for heat (system will switch ON).
During normal operation, the Digistat RF3i will display actual room
temperature continuously.
