Question about Heating & Cooling

4 Answers

Our central heating controls have stopped working. Sunvic select 107XL. No red lights each side even when it is set on 'on' (ie continuous) instead of auto. It still has power; and to try to sort it I pressed 're-set' and it went to 2 PU; and then I reprogrammed it to try to start from scratch; but still no joy. It's about one year old. The same thing did happen about 2 months ago and it then sorted itself within an hour or two, I don't know how. What could it be? in the meantime, no heat (but boiler is working fine for hot water)

Thermostats are just switches, Kind of like a light switch, you turn it on and the light lights, you turn it off and the light goes off.
Thermostats turn them self's on and off, you set the tempature that you want and you set the mode that you want. If it turns on and off by it self then it's working.
Thermostats can't turn on and off both at the same tempature, if you set a thermostat to 70 degrees it may come on at 69 and go off at 71 or vice versa depending on if your heating or cooling.
Thermostats are not all the same,
If you set the thermostat to a comfortable tempature and it keeps you comfortable some what with out you having to jack it up and down then it's working. Thermometers on thermostats are not all that accurate as well as thermostat tempature settings are not all that accurate.

  • If you replace only
    the condenser, you have a "field-matched" system that can be less
    efficient than advertised and that may require more repairs because of
    undetected incompatibilities between the two.

    cooling. A large or multistory house is often divided into several
    heating and cooling zones to improve temperature control. However, this
    type of system is complex and has many more moving parts and controls
    and so may require more repairs.

    Turning off the power to the furnace will allow the control to clear
    the lockout. When you turn the power back on it should be cleared. If
    you do this and the reset button still pops, you will need to call a
    service tech to look at the cause for the resets. Do not continue to
    reset the button as you will end up with a lot of oil in the bottom of
    the heat exchanger and it will cause the tech a lot of grief. If you
    have to call a tech, be sure to tell him exactly how many times you
    have pushed the reset button.

    Its the deinate problem of power cord wire as its getting short internally on the board where it connects to the control board.it needs severe checking with the help of multimeter to resolve the issue.as its not a costly issue but much time consuming and requires a professional technician to repair the power board internally.do not use the unit till it get repaired to avoid the further damage.as because when you on the unit something or other components gets overheated on the board and gets short evry time you on.

    Heating Element

    If lights are flashing on the control panel, the heating element might have burned out. The heating element heats the water up to operating temperature. After a set amount of time if the temperature isn't reached a light on the control panel might start flashing. The heating element can be checked for continuity with an Ohm meter.

    Check Fault Codes

    If the display lights are flashing and there is an error code in the display window, check the wiring diagram and tech sheet in the dishwasher that will provide information on the fault.


    Drain Pump

    If lights are flashing on the control panel, the drain pump might not be working properly. For two-wire drain pump motors check them for continuity using an Ohm meter. If it's defective You'll need to replace it. Drain pumps are not repairable.

    Is the sunvic sp2 a 2channel timer please


    Yes. It appears the Sunvix SP2 is 2-channel timer.
    http://www.sunvic.co.uk/documentation/Programmer_Select_207.pdf

    Two-channel means CH central heat and WH water heater can be programmed separately, and each can have its own timing program.
    pg 3

    The timer offers pre-programmed options for both CH and WH, which can be used, or program your own schedule. chart pg 5 and steps pg 3

    Limitations: both channels operate on same clock time, and dip switch setting. pg 6. So the WH cannot be programmed for 5-2 weekdays-weekends and CH programmed for 24 hour.
    As a convenience for varied work schedules, Sometimes people use the 5-2 weekday-weekend option so 2 days of week can have different programming, and then fudge current day setting during the set-current-time step pg2 so the 'weekend days' are actually moved to wedsday-thursday instead of sat-sun.

    Option: both CH and WH timer programs can be linked and follow same programming by using copy button. pg 5

    Using advance button on either side of timer, pg 3-4, WH and CH timing schedules can be overridden temporarily until next set point is reached. Then regular programming automatically resumes.
    If override or Advance button is pushed for either CH or WH, it reverses whatever programming is in effect. On becomes off, or off becomes on. However if CH thermostat is satisfied and room temperature has not fallen below thermostat set point, then override will not turn CH on, but override will turn CH off. Same for WH override: If cylinder thermostat is satisfied with internal water temperature, the water heater will not turn on and heat more water, but the override can turn water cylinder off.

    Unit requires Cr2033 lithium button battery. Pg 6. Probably lasts 3-5 years. Programming is protected for 30 days from power outage.
    If programming is lost, change battery, the reset timer and reprogram to restore functionality.

    Central heating


    Hi, l doubt this is still an issue for you and l'm certainly no electrician. But many timers seem to be packing in regularly, of all different brands.

    I saw a forum post that directed me to this website: http://www.seered.co.uk/sunvic.htm

    I have had a similar problem with a Drayton SM2 timer - it is basically roasting itself as l speak, and yes l got the red light problem too, light came on, but no heating on, funny smell too. Solved it by flicking the fuse switch on and off (the switch that controls the entire house's electricity). I think powercuts might have something to do with all of this, who knows? But according to the website above, plain shoddy components are the real problem, and yes, the manufacturing companies all seem to be aware of your problems already, however much they deny it when you phone them up and they are chomping away on a sarnie and dismissing your concerns. Make sure you point out if you still have the timer on warranty and get a new one free of charge, pronto.

    And think twice before an electrician tells you it could be a fault with the entire house's wiring. No ... everyone but you and l seem to be aware that timers just break because of their shoddy manufacture. Of course yes it could be a wider problem with the house's wiring, or even the powercuts that l mentioned. Just keep an open mind and don't get ripped off by the manufacturers or the electrician, both vultures l tell thee!
