I woke up this morning and the temperature in my house was 2* less than the set point and the thermostat was showing that AUX heat was activated. I have a 2 year old Climatemaster Tranquility 27 5 ton unit. The unit is equipped with a Honeywell thermostat and TruZone. Closed loop with 600' in three wells. I went downstairs and the looked at the lights on the TruZone and Heat 1 light was blinking. I found the manual and this apparently means my DATS limit was met. I pulled the panel off of the TruZone and watched the display while the unit was operating. The lights for Heat 1,2 & 3 were all lit. The DATS temp slowly rose until it hit 120. My DATS must be set at 120*. My question is: Can I raise the DATS limit so that the unit will run beyond 120*. What is the recommended DATS setting? The outside temperature this morning is 12. High yesterday was 20. Low tonight is expected to be 0. High in the teens tomorrow. I'm worried that with the current set up that 67 may become 65 or less as the temperature continues to drop. The temp this morning was 12*. I'ts expected to be 0* tonight and in the low teens tomorrow. I'm concerned that my inside temp will continue to drop as these low temps continue. Thanks. Kip
