1. Welcome to Credanet II
Before programming your requirements, this section will help you switch on your new Credanet II
system and begin to heat your home
•Your installer will have set your heatingsystem sothat the controller will run the heaters
connected to it according to a pre set profile of times and temperatures.
•A picture of a controller in its normal (Program Run) condition is shown below.
a) Parts of the Credanet IIcontroller
•To get your heatingsystem workingwithout alteringanyof the time and temperature profiles the
Set switch is left in the “PROG. RUN” position.
•If the Clock needs adjustingsee Page 4. (“Setting the day and time”)
IMPORTANT
•The power supplyswitches next to the heaters MUST be left ON at all times.
All the Credanet IIheaters contain an electronic control circuit. The heating will not work properlyif
anyof the switches next to the heaters are switched off.
If no heating is required in a particular zone then the heaters can be switched of using the controller.
See Page 12 “Switching the heating off ”.
Page 4
2. Getting Started
Your heating system has already been programmed with the heating requirements of a typical home.
Once the day and time are correct, your system will automatically start to operate.
NOTE : Please refer to Page 7 (Your Heating Plan) if the heatingrequirements need to be changed.
a) Setting the day and time (Refer to “Parts of the Credanet II controller” on Page 3)
Check in the displaythat the dayand time are correctlyset.
If not, open the pull down flap on the front of your Credanet IIcontroller.

buttons to change the time
(e.g. Changefrom 12:01 to 12:15)
Page 5
b) Programme Run (Pre-set programme)
•When the Dayand Time are correct : Slide the SET switch to PROG. RUN
Your Credanet IIsystem is now readyto operate ~simplyclose the flap andyour heatingwill follow the
pre-set programme.
NOTE
If the word OFF appearsin the displayabove anyof the “+” or “ -” buttons, you will need to open the
flap and press the SELECT button below them, before your system will operate. The word OFF will be
replaced bya number.
3. Planning your heating
Your installer will have programmed your Credanet II Controller so that the heating can be set to
different temperatures in different parts of the house. This section explains how to alter these to suit
your individual needs.
a) Room Allocation Chart
•The heatingin your propertyis sorted into zones.
•Each zone, and all the heaters in that zone, can be set to its own temperature and timings.
Example showing Zones within a property :
This Controller has been programmed
with three zones. (Zone 1 downstairs
and Zones 2 and 3 upstairs).
Azone is agroup of one or more rooms
with one or more heaters.
ACredanet II installation can be
programmed with one,two or three
zones. ZONE 1
ZONE 2 ZONE 3
Example of a completed RoomAllocation Chart:
An example of a completed Chart is shown below.
In this completed RoomAllocation
Chart the propertyhas aCredanet II
controller programmed as follows :
Zone 1
LivingRoom with 2 storage heaters
DiningRoom with 1 storage heater
Zone 2
Kitchen with 1 storage heater
Zone 3
Bedroom 1, 2and 3, each with a
Panel radiator.
Note
This property also has a“stand
alone” heater fitted inthe H
allway.
This is not part of the Credanet II
heating system but is detailed in
this table for clarity.

b) Your Heating Plan
Your heating system has already been programmed with the heating requirements of a typical home.
Once the day and time are correct (see Page 4), your system will automatically start to operate.
NOTE
•In some situations the HeatingPlan programmed into the Controller will have been “Locked” bythe
Installer so that it cannot be changed. (This is usually on instruction by the property specifier).
If the pre-set heatingscheme is not to your requirements then it can be changed to suit your individual
plan.
Before you plan your heating, take a look at the pre-set programme below,alreadyprogrammed into
the controller. This is the programme that is alreadyset foryour system, and which you have started in
“Section 2 – Getting started”.
What is “Comfort temperature”?
The comfort Temperature is how hot or cold you
want the room to bewhen you are likelyto be
usingit. You can setthis to anylevel you
choose, and it is measured in °C. (equivalents in
°F shown below)
°C
14°
15° 16° 17°
18° 19° 20°
21° 22°
°F
57°
59° 61° 63°
64° 66° 68°
70° 72°
What is “Fallback temperature”?
When you aren’t usingaroom,you can
programme Credanet II to let the temperature
“fall back”to alower level, and the level you
choose for this is called the fallback temperature.
Ifthe temperature falls below this, Credanet II
bringsit back up to the fallback level and keeps
it there ~preventingtheroom from becoming
too cold.
Use the table on the nextpage to plan out how youwant your heatingto runon each dayof the week.
This will help you when you come to programme your planinto the controller, and will make a useful
record ofyour settings.
NOTES
•For each Zone and Day, the controller will not allow overlappingTime slots to be Set.
•Tryto avoid settingthe Fallback temperature more than 4°C lower than the Comfort temperature.
(A low Fallback temperature will cause the Credanet II system to use more peak rate and less cheap
rate electricity. The running costs are likely to be higher).
