[. . . ] Pressing and releasing these buttons changes the time by one minute, holding these buttons down changes the time quickly. When the time is correct press the PROG button to start the clock; now only the colon and day number are displayed, (see fig. Use the + and buttons to select the correct day number. (It is intended that day 1 is Monday, therefore days 6 and 7 are Saturday and Sunday - the weekend). [. . . ] It WILL NOT provide frost protection in unheated areas, and may not provide frost protection in heated areas not controlled directly by the TP5E. BATTERY REPLACEMENT When the batteries approach the end of their life, a battery symbol blinks in the display (see fig. 12 symbol appears both batteries should be replaced with high quality alkaline cells. 15 days after the symbol appears the TP5E will switch off. While the battery symbol is blinking the batteries may be changed without loss of time or programme. Have the new batteries unwrapped and ready, slide the battery cover fully off to the left, remove the old batteries and fit the new ones WITHIN FIVE MINUTES. The TP5E will continue to function according to the automatic programme. Should the display ever become blank during normal operation the batteries will have to be renewed, the unit RESET, and the time, day and programme re-set as required. Fig. 7 TIME OR TEMPERATURE DISPLAY The TP5E will always display the time and required temperature after a RESET. Once the switching times and temperatures have been set and the Fig. 8 unit returned to the RUN mode, the actual room temperature can be displayed instead of the time. To change between time and temperature display press the + and - buttons together. 8 is a typical temperature display showing the actual temperature, the required temperature, and flame and thermometer symbols. The flame symbol appears in either time or temperature displays when the TP5E is calling for heat. MANUAL OVER-RIDE The programmed control temperature may be changed temporarily using the s and t buttons until the required Fig. An s or t arrow will appear in the display as a reminder that the programmed setting has been overridden, (see fig. This over-ride is cancelled at the next programmed switching. WEEKEND into WEEKDAY OVER-RIDE To use days 6 & 7 settings during any of days 1 to 5 press the s and t buttons together, (see fig. This over-ride is cancelled by selecting Constant Temperature Control (see below) or when the time reaches 2:00. CONSTANT TEMPERATURE OVER-RIDE To set the TP5E to control at a constant temperature of 5°C press the s and t buttons together, once from Weekend/Weekday over-ride or twice from RUN mode. The required constant temperature may now be set using the s and t buttons, and can be anywhere in the range 5°C to 30°C. At 5°C a snowflake symbol appears in the display (see fig. [. . . ] Selecting the control mode The TP5E can operate either in on/off control mode or in chrono-proportional control mode. This is selected by means of a small link on the rear of the product (see fig. 15 for location) The unit is factory set to on/off control with the link in place. When in on/off mode the thermostat cycles the heating on and off within it’s switching differential. If chrono-proportional control is selected the thermostat learns and attempts to reduce the switching differential thus improving comfort. t s Fig. [. . . ]
