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 heating system so that 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 II controller

• To get your heating system working without altering any of the time and temperature profiles the

Set switch is left in the “PROG. RUN” position.

• If the Clock needs adjusting see Page 4. (“Setting the day and time”)

IMPORTANT

• The power supply switches next to the heaters MUST be left ON at all times.

All the Credanet II heaters contain an electronic control circuit. The heating will not work properly if
any of 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 ”.

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.

Check in the display that the day and time are correctly set.
If not, open the pull down flap on the front of your Credanet II controller.

• Slide the SET switch to CLOCK

• Use the left hand “+” and “ - ” buttons

to change the day

(e.g. Change from MON to WED)

• Press the left hand SELECT button

when the correct day is shown.

• The time will flash

• Now use the left hand “+” and “ - ”

buttons to change the time

Your Credanet II system is now ready to operate ~ simply close the flap and your heating will follow the
pre-set programme.

flap and press the SELECT button below them, before your system will operate. The word OFF will be
replaced by a 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 heating in your property is 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).

A zone is a group of one or more rooms
with one or more heaters.

A Credanet II installation can be
programmed with one, two or three
zones.

ZONE 1

ZONE 2

ZONE 3

Example of a completed Room Allocation Chart:

An example of a completed Chart is shown below.
In this completed Room Allocation

Chart the property has a Credanet II
controller programmed as follows :

Zone 1

Living Room with 2 storage heaters
Dining Room with 1 storage heater

Zone 2
Kitchen with 1 storage heater

Zone 3
Bedroom 1, 2 and 3, each with a
Panel radiator.

Note

This property also has a “stand
alone” heater fitted in the H

allway.

This is not part of the Credanet II
heating system but is detailed in
this table for clarity.
