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.

I can't find an instruction manual for a Sunvic 307 xls online


This is simple to light. Turn the selector switch to pilot and push it down then push the striker button and watch it light. Hold for 30 seconds and then let off. Turn the selector switch to the desired comfort level and it will work.

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!
