Upon arrival I confirmed price with customer and explained the Intellistart so they knew what they were buying. Shut down unit and installed Intellistart. Wired with comfort alert and confirmed wiring with schematic. Returned power to unit and tested. Unit operating normal. Customer mentioned that they donâ€™t feel as comfortable at same temperature after pm service. Found unit operating normal with normal deltas at all components. Found humidifier has too much water flowing thru. Reduced water pressure at piercing valve so pad doesnâ€™t get over saturated and more humidity is produced.
On arrival set units to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections inspected coil,heat exchanger,safeties ,blower,also inspected ductless systems.all units are operating normal

I operated the unit on heating mode. I increased manifold pressure from 3.0 to 3.5 iwc. The temperature rise was close to 70 degrees which is at the upper limits for the units heat rise. I calculated cfm and found it to be too low. I increased blower speed to med high from med low. This will bring temperature rise into a more comfortable range and be better for the equipment. Otherwise I checked the rest of the system and found it to be in good working order. Unit operating normal. Customer already received an estimate to replace the humidifier, which was my only recommendation.
Washed out prefilters for customer. Operated the unit on high heat mode. Increased gas pressure to the manifold to 3.5iwc. Then I found temperature rise was too high. Most likely someone lowered the gas pressure to decrease temperature rise instead of calculating cfm and increasing the blower speed. I used dip switches on the board to increase the cfm to 1200 from 850. I checked the electrical wiring and electrical systems, all are within specification. Unit operating normal. I am sending a quote for a replacement humidifier.
I replaced the filter upstairs with one provided. I went to test auxiliary heat first but it would not come on. I found the wiring was incorrect. I fixed this issue and the auxiliary heat came on. I then ran in second stage heating mode. I decreased blower speed to increase delta temperature. I pressurized both ground loops to 65psi. I confirmed proper flow rate on each loop. The package unit had a faulty capacitor which was replaced. I checked the electrical wiring and electrical systems, all are now within specification. Both units are operating normal.
