  • the heating off switch may be located near the front door of the dwelling or house being heated for easy convenient usage. Upon pressing, the system turns off all zones that are being heated and maintains a temperature not less than 3 0 C lower than the preset living temperature in the house.

This reduced temperature should provide significant energy savings through the day.

  • the Advance facility is a non menu driven option that is accessed purely from the ZONE buttons.
  • the effect of pressing a ZONE button is to immediately switch on that ZONE for 1 hour plus the time to the next scheduled 1/4 hour update.
  • the blue LED associated with that ZONE will also light for the duration. Whilst any ZONE is in Advance, a second press of the ZONE button will switch off the LED instantly but not that zone until the next 1/4 hour update.
  • the control will house a temperature sensor and DC amplifier fed to an A-D input so that it can be used to limit the maxiaium temperature of the-heating. If the temperature set in the menu (15 - 25C ) is reached, the heating will shut down regardless of the zone requirements. This function can be switched off or replaced with an external contact type room stat in the menu.
  • frost stat The same temperature sensor as used for the room thermostat can also be used as a frost stat. When no heating is being called for the sensor is to be checked every 15 minutes to see if the room temperature has dropped to or below 3C. If it does frost mode should commence. Frost mode can also be initiated by either an external contacttype. stat orby either of the pump fail sensors reading 3C or less. There. is no menu requirement for frost protection.
  • frost mode When frost mode is triggered the control will open all the radiators and run the pump continuously until the trigger is removed. After 15 minutes, if the water temperature as measured by either of the pump fail sensors is above 3 C, stop the pump and check again every 15 minutes. If the water temperature is not above 3C the boiler and pump are switched on for 15 minutes. The room stat should then read above 3C and the system reverts to normal frost monitoring. If the room stat still reads 3C or less the boiler should stay on for a further 15 minutes until it does read 3C+.
  • External room thermostat fault indicate “ROOM STAT FAULT” and the control then refers only to the internal room stat reading, even if switched off in the naenu:
  • External frost stat fault indicate “FROST STAT FAULT” and the control then refers only to the internal frost stat reading, even if switched off in the menu.
  • Pump stat fault indicate "PUMP STAT FAULT”, disable the pump monitor routine and refer to the other pump stat, if working, for frost protection. If neither pump stat is functional, use the frost function of the internal sensor.
  • each valve 2b is of a pulse operated solenoid type for example as manufactured by a company called General Imsubs of the following specification:-
  • Coil Type Self latching coil, intermittent duty.
  • Power supply system Capacitor discharge, reversible polarity type. Valve is operated t ⁇ y supplying current through capacitor discharge type power s ⁇ ppiy. When current is supplied on one polarity valve is actuated and remains in same position till power is supplied in reverse polarity. See Diagram 1.
  • Coil life Minimum 250 000 cycles.
  • Water Flow rate 5 LPM at 0.3 bare pressure and less than 35 LPM at 6 bar pressure.
  • Position 1 if valve is in closed condition and coil is supplied voltage by discharging 4700 MFD capacitor charged by suitable power supply (pulsed current)* than valve comes in open position and remains open till supplied current as shown in position 2
  • Terminal 1 - ve Terminal 2 +ve
  • Position 2 when valve is opened by supplying current as mention in position 1, it can be closed only by supplying current as mentioned above.
  • Valve remain in off position till power is supplied as mentioned in position 1, Power- is supplied by discharge of 4700 MFD capacitor (pulsed current).
  • the main advantage of such valves is that only a brief pulse of low voltage DC (6- 12 volts) is required to change the operating status of the valve from 'open' to 'closed' and vice versa.
  • the state of the valve is changed by reversing the polarity of the supplied signal pulse.
  • no heat is generated in consequence of trying to maintain a changed state and the life of the valve is not limited by the burnout time of the coil.
  • the body of the valve 2b has a mechanism (in common with conventional solenoid valves) that utilises water pressure to hold the valve in the selected state.
  • the valve 2b can remain in either state by residual magnetism rather than by the application of an electromagnetic force.
  • the 'Combi / conventional switch' is a software switch and is set during the initial programming of the control. Its function is to determine the functionality of zone 8 of the control. When set to 'Combi' zone 8 works exactly as the other 7 heating zones. When set to 'conventional' zone 8 becomes the hot water timer and control. An external hardware adapter is required to interface the control to either an immersion heater or 3 port valve.
  • the 'summer switch' is a mechanical latching switch located under the front flap of the control. Its function in the 'summer' position is to disable the heating programs whilst maintaining the frost protection and manual override facilities. If 'conventional' has been selected during initial program setup, zone 8 which is the dedicated hot water control will continue to function.
  • This facility can only be used with a combi boiler or a conventional one where hot water heating control is not required. It is set by configuring the control during initial set up as a 'conventional' boiler. Its function is to maintain heat to a zone that requires heat all year round regardless of the summer switch position. This could be a drying / airing cupboard, shower room or the area used by an ill or infirm person where a minimum temperature is required all year round. An additional room thermostat should be installed and wired as if it were the hot water tank thermostat as used with a conventional boiler.
  • That zone can be switched on instantly by pressing the button once. This will override the program and keep that zone on for one hour from the next quarter hour zone update time. If the button is pressed twice within a 5 second period then that zone will override on for 2 hours from the next quarter hour zone update time. If the button is pressed three times within a 10 second time period the function will be cancelled and the override will cease.
  • This feature can be used at any time and as many zones as required can be overridden simultaneously.
