  1. you told a supplier how much money you had to spend? Ouch.
  2. are you absolutely sure the fault is in the cable rather than the light? the windy-on plastic things are called "wire nuts" and we're not in the US so you'd be better off thinking about Wagos...
  3. timezone can work two ways- full on/off, or programmable setpoints. Enable it only for setpoint, then add whatever timezones you need in C105-108. I *think* that these setpoints are then fed into the WC, but I'm not sure if they act as a minimum or maximum...
  4. there's a bit of blurb in the v6.6 manual- and IIRC something slightly more detailed bit chenglish in the original Sprsun manual. But broadly, Day mode allows use of the full performance envelope, Night caps it for low noise, and low is weather comp. However, even the non WC modes throttle compressor speed based on ambient temp so... what might be useful for you is U02- startup differential and shutdown differential. They control how much below setpoint the unit starts, and how it slows down as it approaches setpoint.
  5. Do you really need to weather-compensate the DHW temp? I use the timer function on our iVT9 for what you're proposing, basically doing a set-back of DHW temp overnight and then boosting it just before the end of the E7 timeslot, ready for showers
  6. check tinternet for piccies of the bare valve so you know where to aim for
  7. are you sure the contactors aren't the "other" way round, or their stats set so that the "wrong" one is doing the heavy lifting?
  8. I think the Graf is like the Solido, with a pumped discharge using an airlift? @flanagaj I believe there's now a version of Solido with Nitrate reduction using a dosing system- have you seen it?
  9. it answers the question tho
  10. which uses more tonnes of stone?
  11. I'd presume so, but have never tried it
  12. IIRC it's not a solenoid but rather an electrically-heated wax motor. Takes a few minutes to open and close as it heats or cools.
  13. buy the whole thing justincase, but only send the plug?
  14. you can, if your careful put SDS in a normal chuck... and a cheap TCT core will do it
  15. a/c linkage is simple startup yep.
  16. yep, that contact overrides the current mode set in User Mask, according to Chris...
  17. not always. SBRs do an aeration/ settle/ decant cycle, within a single chamber.
  18. Yes it is a pop up bar and needs to be moved around in a van maybe could have mentioned that earlier?
  19. practice and youtube. There were some great videos from (IIRC) Volvo in the US that helped me understand some of the stuff I'd watched my groundworker pal do so delicately
  20. If you only want cheapo softwood linings, Howdens do some useful sizes, like 115mm for 89CLS + PB
  21. post a photo of the top of the soil stack at the roof
  22. getting that glazing bar at the right height can reduce costs too as it can allow a downgrade in the glass above it. Our archtect designed this into our large front windows.
  23. blue square thing looks like a transit foam that hasn't been removed from the unit?
  24. Our Bronpi does the same kind of thing occasionally, I think the term is "cold plug". Gotta use a bigger than expected starter to get things moving.
