The unit must be installed by a competent electrician and the installation should conform to IEE Wiring Regulations. The supply to this unit should by wired via a full disconnect in accordance with BS EN60730-1, i.e. one which provides air gaps of at least 3mm in both poles of the mains, and incorporates a 3 amp. fuse. It is strongly recommended that solid conductors be used.

Installation and Wiring
1. Select the desired fixing position for the heating controller. 2. When fixing the wallplate remember the connections are at the top and the vertical centre line of the unit is at the position shown C/ L, (which is at the right hand edge of the terminal 4 recess.) 3. Fix the wallplate to the wall or flush mounted box as required. 4. Surface cables can only enter from below the unit. If mounted on a flush mounted box, cables can enter from the rear through the aperture in the wallplate. 5. Whilst the unit does not require an Earth connection, two terminals are provided on the wallplate fot Earth continuity purposes. 6. Locate and fix the Remote Sensor, this should be as per room thermostat i.e. 1.5m above floor, away from draughts and extraneous heat gains. Remote Sensor wiring should be in 1mm2 Mains Voltage Cable (not flexible cord). Sensor cable must not be run parallel to mains cable in order to avoid pick-up. 7. Overleaf are typical wiring diagrams which together with the information above should enable all the services to be connected correctly. 8. Ensure all dust and debris are cleared from the area. 9. The unit may now be set for either 24 hour or 5/2 day operation. It is supplied ready for 5/2 day operation, and in the unlinked PUMPED primaries condition. To convert it to 24 hour operation move the switches 2 and 3 on the back of the unit to the 24 HR position. To operate in the linked GRAVITY condition, for instance in a system having gravity primaries with no control of gravity circuit flow, move switch 1 to the GRAVITY position. 10. Locate the module on the two locating lugs on the top of the wallplate and hinge downwards to fully engage the fixing screws in the slots at the bottom of the module. Tighten the screws. 11. If the unit is disconnected from the mains supply, either intentionally or due to a power-cut, the life-long integral battery will retain both time-of-day, day, and the programmed times for fifteen days. During this period the display will appear normal, except for the blinking battery symbol, with the clock keeping time. On the sixteenth day of continuous interruption of power, the clock will stop and the display will become blank, except for the colon which will be on continuously. However, the programmed times and temperatures will be remembered. When the power is restored

(after more than fifteen days) the unit must be started by pressing any key. The clock will restart at 12:00PM (MO), and all that need be done by the user is to set up the time-of-day, (and day-of-week if the unit is 5/2 day mode). 12. IMPORTANT: To remove unit from wall, isolate power supply. Slacken the two screws at the underside of the module and ease the bottom of the module away from the wall to disengage from the wallplate. Lift the module off the two locating lugs on the top of the wallplate.

TP9 Electronic Central Heating Controller
Programmable Room Thermostat plus Domestic Hot Water Timer

USER INSTRUCTIONS
General Description
The TP9 can have a room temperature setting range of either 5°C to 30°C or 16°C to 30°C. Switch 4 on the back of the module is used to choose which range. In all display diagrams the 5°C to 30°C range is used. The TP9 will control your Central Heating and Domestic Hot Water system in any one of three ways: 1. Automatically adjust room temperature up to six times a day providing comfort with economy, and switch on the hot water heating circuit twice a day. Switch off the water and control the heating to provide a constant low room temperature while the home is empty for extended periods. The display will appear as in Fig. 2. (N.B. When the unit switches the CH on, the HW will also switch on if the unit has been set for linked GRAVITY operation). Operate as a 2 ON/2 OFF Hot Water timeswitch during the summer, or other times when Central Heating is not needed. The display will appear as in Fig. 3. (If the room temperature falls below the low setting displayed, the heating will switch ON). If the minimum temperature you can select is 16°C and you do not want the heating to switch ON at all whilst operating in this mode, you should ask your installer to fit an extra switch to the CH output. He can get the information he needs to do this from our Technical Services Department.

Switching from one type of operation to the next is acheived by pressing both temperature adjustment buttons (s , t) together. While operating as 1 or 3 above, the +1HR ON button can be pressed at any time to heat the Hot Water for an extra hour. Fig. 3. Hot Water Only Mode, (Central Heating will switch on if room temperature falls below 5°C.)

First-Time Installation
When the unit is first removed from its packaging the display will, most probably, just show two dots (the colon). THIS IS NOT A FAULT, but a battery saving feature. Once fitted in accordance with the Installation Instructions supplied and the mains electricity is switched on, the unit should be activated by pressing any button and then RESET.

Reset
Reset the unit by pressing and holding down the four buttons; TEMPERATURE up (s) and down (t), minus (-) and plus (+) all at the same time, for at least two seconds, until the display becomes completely blank. Release the buttons, and the unit will begin automatically with the display similar to Fig. 1. i.e. 12:00PM with the colon blinking, 16°C, and the day (MO) shown if the unit is set for 5/2 day operation.

Automatic Operation
While the colon is blinking the clock is running and the unit will control your Central Heating (CH) and Domestic Hot Water (HW) in accordance with the set programme. The unit incorporates a Factory Pre-set Programme which is detailed in table 1 overleaf.

Setting the Clock Checking and, if required, changing the Factory Pre-set Programme.
To set the clock to the correct time and check the factory pre-set programme, or change it to suit your lifestyle, use the PROG, minus (-) and plus (+) buttons. Starting from the RUN mode (with the colon blinking); each press of the PROG buttons steps through the checking and setting sequence, which is listed in table 2 overleaf.

T p rod uc t c om p lies w ith the follow ing EC Direc tives: his Electro-Ma gnetic Compa tibility Directive. (EMC) (89\ 336\ EEC), (92\ 31\ EEC) L ow Volta ge Directive. (L VD) (73\ 23\ EEC), (93\ 68\ EEC)

Follow this sequence to check/change first the time-of-day, then the times and temperatures, and finally the hot water ON/OFF times. If you change any or all of the time and/or temperature settings, record the new ones on the space provided in table 1. You may reinstate the Factory pre-set times and temperatures at any time by performing a RESET as described earlier.

When running normally the unit will control the heating system at the chosen temperatures. Domestic Hot Water Times To over-ride the programmed temperature use the (s or t) buttons. An up or down Setting Function Pre-set arrow will appear in the display as a reminder that the programme is over-ridden. The selected temperature will last until the next programmed change. A On 6:30AM When the Central Heating is ON, a flame symbol appears in the display and the red CH indicator illuminates. b Off 8:30AM When the Hot Water is ON, a tap symbol appears in the display and the HW indicator illuminates. C On 5:30PM When the WATER +1 HR ON button is pressed, a O symbol appears in the display. This will extend an existing ON period by an hour, or switch ON for just one hour d Off 10:30PM if the Hot Water is OFF. If the unit is disconnected from the mains supply, either intentionally or due to a power-cut, the life-long integral battery will retain both time-of-day, day, and the programmed times for fifteen days. During this period the display will appear normal except for the blinking battery symbol, with the clock keeping time. On the sixteenth day of continuous interruption of power, the clock will stop and the display will become blank, except for the colon which will be on continuously. However, the programmed times and temperatures will be remembered. When the power is restored (after more than fifteen days) the unit must be started by pressing any key. The clock will restart at 12:00PM (MO), and all that need be done by the user is to set up the time-of-day, (and day-of-week if the unit is 5/2 day mode).

LIMITS OF ADJUSTMENT FOR TIME SETTINGS.
Time settings 1 and A can be at any time of the day or night, but would normally be in the morning. Each of the time settings 2 to 6 and b to d can at any time between the preceding setting and 1:59AM. Time settings 2 to 5 and b and C can be set later than the next setting, but doing this changes the next setting as well e.g. changing setting 2, in table 1 above, to 3:00PM would also change settings 3 and 4 to 3:00PM. This feature prevents times being set out of sequence. If you wish to return to the pre-set programme, reset the unit as described overleaf.
