Frequently Answers and Questions

How do I install this geothermal heat pump?
Follow the installation instructions provided in the manual to install the unit correctly. Ensure that you consult with a qualified technician for guidance and assistance.
What are the acceptable operating voltage ranges for the 240 and 208V taps?
The acceptable operating voltage ranges are listed in Table 2. For 240V tap, the range is 253 - 216 volts. For 208V tap, the range is 220 - 187 volts.
What should I do if the high pressure switch opens?
When the high pressure switch opens, the compressor contactor will de-energize immediately. The lockout timer will go into a soft lockout and stay in soft lockout until the high pressure switch closes and the delay on break time has expired. If the high pressure switch opens again in the same operating cycle, the unit will go into manual lockout condition and the alarm relay circuit will energize. Recycling the wall thermostat resets the manual lockout.
