Sounds like the lockout is not working. That makes sense, as the manual says you need the outdoor sensor for the lockout to work. The sensor is...
That rule of thumb might work for straight pipe out and back in its own trench. However, the overlapping coils in a slinky mean you will need a...
It sounds like the HX might be freezing up. A 15% glycol solution only gives you freeze protection to about 26 degrees. Most GSHPs have a freeze...
Domestic water needs high pressure and low volume. GSHPs need high volume and low pressure. These are conflicting requirements, so it ends up...
You should have been left a copy by your installer. Search for im1578ew.pdf
You need 1.5 GPM per ton of capacity. Yes, a pressure reducing valve, as water pirate suggested, could keep the pressure constant at 10 PSI or...

I don't have that knowledge, but it's a problem others have already solved. Maybe waterpirate can suggest something.
The outdoor temperature sensor is included with the Intellizone2 kit. If your installer did not install it for you, I'd suggest you ask them about...
You need very little pressure for open loop. Only about 5 PSI minimum.
There is no stage 2 wire in the 7 Series. The thermostat uses RS485 serial data protocol (similar to RS232 in your PC) to communicate with the...
The lockout setting makes it so the AUX will not come on unless the outside is greater than 10 degrees. You can set 0, 5, 10, ..., o4 40. This...
I have the same situation: 4T WF7 with 2 zones (Intellizone 2) in a part time hone. I keep it at 62 when I'm not there. I used 55 in my old...
I can't list all units that support variable flow, but they include Waterfurnace Series 7 and Series 5 and Climatemaster Trilogy TZ. These all use...
Open loop will require 1.5 to 2.0 gpm per ton of capacity. Some two-stage systems have the ability to lower the GPM when on stage 1, which should...
