  1. My dealer is in contact with the distributor.

    My dealer is in contact with the distributor.
  2. I've turned off the exterior shut-off thermostat...

    I've turned off the exterior shut-off thermostat and it solved part of the problem. Why? I don't know, because this thing was there to turn the HP off in really cold weather. Now, the HP no longer...
  3. Nobody knows? Sometimes +2 flashes On and Off...

    Nobody knows?

    Sometimes +2 flashes On and Off and sometimes it's fixed.
  4. System On +2 (with the +2 flashing - Why?)

    System On +2 means that the HP is running at its higher power.

    What does it mean when the +2 indication flashes?
  5. Turning off the Shut-Off thermostat seems to help.

    I understand. Thanks for your help. My dealer wants to have my system working as designed, and the tech seems to understand how these machines work. Moreover, he'll be getting help from the...
  6. My WR thermostat allows short/long cycling in AC...

    My WR thermostat allows short/long cycling in AC and Heating. I'll try the longer cycling in Heat.

    Dealer's tech doesn't understand how the auxiliary electric heat can prevent the HP from running,...
  7. I'm already working with the installer on this...

    I'm already working with the installer on this problem. I've printed and given him a copy of this whole discussion, in order to help him solving my problem...
  8. Milk man, please refer me to the website.

    Milk man,

    Would you refer me to the website where you found this sequence of operations.

    Thanks.
  9. Did you really mean too many cycles?

    Dear beenthere,

    Did you really mean too many cycles? I may be wrong, but I would think "not enough cycles" would make heating overshoot the thermostat's setting, not too many cycles.

    Thanks.
  10. I'm impressed. Like I said earlier, eventually it...

    I'm impressed. Like I said earlier, eventually it has to get close to 1:1 and it's then no longer economical to use the heat pump, because of wear on the machine. How do I determine at what temp I...
  11. When it gets closer to 1:1 then I guess it's no...

    When it gets closer to 1:1 then I guess it's no longer economical, figuring the wear on the machine.

    At what temperature should I set the outside shut-off thermostat?
  12. I wonder where these machines can find enough...

    I wonder where these machines can find enough energy to heat a house in -5 Fahrenheit air.
  13. I'm surprised, because I've been told many times...

    I'm surprised, because I've been told many times that below 10 degrees Fahrenheit (-12 degrees Celsius) there was no economical advantage in using the heat pump.
  14. It can get quite cold here at night, like -5...

    It can get quite cold here at night, like -5 Fahrenheit or even less. and I've been told that at these low temperatures, the heatpump only gives 1kw of heat per kw of electricity.
  15. At what temp do you recommend I turn it off?

    At what temp do you recommend I turn it off?
  16. Outdoor thermostat.

    I have an outdoor thermostat, used for shutting down the heat pump below 14 degrees Fahrenheit. Then it's electric heat only.
  17. I understand that these figures are from the...

    I understand that these figures are from the MBE/MBR Installation instructions. This I have.

    Mine is a two-stage cooling/heating model, though. My guess: Maybe either figure 28 or 29, on pages 17...
  18. Thanks to all for your help.

    I understand. I'll ask the dealer. Thanks to all for your very kind help.
  19. I'll ask the dealer for the manual.

    Thanks. I'll ask my dealer to get it...

    This sure looked like it, though:

    http://www.acwholesalers.com/EasyEditor/assets/new%20goodman/dsz%20specs/dsz18_service.pdf
  20. Service Instructions as PDF File.

    Is this it:

  21. Manual probably got thrown away...

    Then it was probably thrown to the garbage or recycling with the various boxes... I'll ask the dealer for another copy, unless I can find it on the internet.
  22. Where can I get this manual?

    Does my dealer have this manual?

    Is it available on the internet?
  23. Can it be set to use less than the 20kw of aux heat?

    Why cool air? If I had two 10kw breakers, and turned one off in warmer winter weather, wouldn't I just have less hot air coming out?

    Is there another way of setting the system to use less than the...
  24. Why is the thermostat (set for short cycling)...

    Why is the thermostat (set for short cycling) keeping auxiliary heat on (this is not residual heat) while it's been overshooting its set temperature by almost two degrees? This only happens in aux...
  25. Can the fan run slower in auxiliary heat?

    Great idea. I'll check with the dealer if I have two breakers, and will have him do this modification, if not.

    The fan runs at a very high speed in aux. heat. I'd say it's running faster than when...
