I've always had a problem when the weather warms up at all. The gear won't
come down unless I crack open the dump valve for a second. I don't like doing
that but if I don't I can't get the pressure out of the low switch to start
the pump. I've tried adjusting the pressure switches a little each way to see
if it would help but it doesn't. Maybe a bypass relay to start the pump in the
down position would be the answer.

[Randy, it almost sounds like you're fighting an internal pump issue. If you've got the pressure switches set to their lowest possible settings to achieve consistently reliable operation at _some_ particular temperature, unless there is something restricting the internal flow there is almost no reason that temperature should be able to be removed from the equation (ie, temp increase = pressure increase, which should be dealt with already). Isn't this one of the
symptoms we hear about so often with the reversed spool valve? Greyhawk...??? <Marv> ]
