INTRODUCTION
A heating controller is used to switch the heating
system in your home on and off as needed. It works by
controlling the heating boiler according to a series of
programmed settings that take effect at different times
of the day.
The SP220 from Salus Controls is a stylish and accurate
twin channel programmable heating controller
designed for independent control of central heating
and hot water. Fitted with a large, easy to read Liquid
Crystal Display (LCD), this controller has been
specifically designed to be used for 230V AC heating
applications.
The use of the revolutionary Touch Ring technology makes for simple usage, and is coupled with
a unique, smart design and the ‘one touch’ operation makes the SP220 easy to operate.

INSTALLATION
Please read the important safety information at the start of this manual before you begin to install
the device. The ideal position to locate the SP220 programmable heating controller is about 1.5m
above floor level. It should be mounted in a location where the controller is easily accessible,
reasonably lit and free from extremes of temperature and draughts. Do not mount the controller on
an outside wall, above a radiator or in a location where it may be subjected to direct sunlight.
The SP220 should be mounted in a location where it will not come into contact with moisture or
condensation, as this can affect the Touch Ring operation.
To ensure trouble free reception for both the Radio Controlled Clock (RCC) and the Radio Frequency
(RF) signal, always ensure that the programmable thermostat is mounted away from any possible
sources of interference (such as radios, TV sets, computers, etc.), and is not mounted on or in close
proximity to large metal objects. Installing the SP220 in enclosed areas such as cellars and basements
is not recommended.
The electrical connections to the SP220 are made to the terminal strip within the controller itself.
Connection details are shown below - no Earth connection is required for the correct and safe
operation of the SP220.

After installing the controller in a suitable location, wiring connections can be made as shown above.
The following criteria apply to the installation:
• The incoming AC mains supply should be 230V AC and fused at 6 Amps.
• Optimum cable size for installation is 1.5 mm2; wiring colours should be in accordance
with the current requirements of the IEE Wiring Regulations.
• Cable entry should be made at the cable entry point
• All wiring connections should be securely made, and be firmly gripped beneath the terminal clamp.
Do not restore the mains supply to the system until all associated items are fully installed.
NOTE: All electrical installation work should be carried out by a suitably qualified Electrician or other
competent person. If you are not sure how to install this controller consult either with a qualified
Electrician, Heating Engineer or your boiler / heating system supplier for advice on how to continue.
Do not remove or refit the SP220 without the mains supply to the system being isolated.
AFTER INSTALLATION
After completing installation and powering up the SP220 for the first time the controller will behave
in the following way:
All the indicators on the display and the backlight will be turned on for a few seconds. The internal
firmware version will then be displayed for a few seconds, and the SP220 will then operate in Normal
mode (controller output OFF).
If the Reset Button is pressed, the SP220 will behave in the
same way as described above and any previously saved user
settings will be deleted and overwritten with the default
settings, except when the SP220 is in SERVICE mode.

BOOST MENU
The BOOST menu allows the use of a temporary override mode which allows the user to override the
current programme settings and turn the heating and/or hot water on for a preset period. This mode
is activated by selecting the BOOST menu – this mode allows you to override the current programme
settings up to a maximum of 9 hours. The options available will differ slightly depending on whether
the controller is set for pumped (P) or gravity (G) operation.
Pumped Operation:
Central Heating Hot Water
c0 Heating override OFF h0 Hot Water override OFF
c1 – c9 Heating override active h1 – h9 Hot Water override active
for selected period for selected period
If the controller is set for Pumped operation, then central heating and hot water override settings
can be set independently.
Scroll through the setting by using the Touch Ring. Changing the settings will increase the duration
of the override by one hour, to a maximum duration of nine hours. Increasing the setting beyond this
level will roll the setting back to 0 and disable the temporary override. Confirm the heating setting
by pressing the OK key, and then change the hot water setting in the same way.
