PENTING: For WG2A, WG1AH, WG2AH and WG2AD unit’s, if using a cased coil over a furnace, do NOT program your thermostat for dual fuel mode or, use the furnace settings. Leave the thermostat set to electric aux. heat, otherwise, you may interfere with proper PLC function. Follow the dual fuel function option for the unit model you are installing. This information is detailed in your unit installation manual. You will also want to check the aux. heat cycle rate (CPH) setting in the thermostat and set this to 1 or, the lowest available value depending on your thermostat brand and model.

Smart Logic Controller

WG2A Forced Air Only– List of functions

1. The PLC checks that the LOW/HIGH pressure and discharge temperature switches are made. An open pressure switch input has a 60 second delay before setting a lockout and fault signal to
   “X”. During this 60 second time period, the compressor will only operate in 1st stage mung menehi sistem kesempatan kanggo waras sadurunge nyetel kunci hard metu. Iki kanggo nyegah telpon gangguan, utamané ing awal mangsa cooling nalika Earth Loops ing paling kadhemen. "X" disetel karo kondisi lockout hard. Nguripake vol rendahtage menyang unit kompresor mati banjur bali ing ngreset lockout anggere ngalih suhu discharge ora mbukak. Ngalih suhu discharge duwe tombol reset manual. Ngalih suhu discharge mbukak bakal tansah mbutuhake reset manual bebarengan karo vol kurangtage siklus daya. Saklar tekanan otomatis.
2. A “Y1” call starts 1st stage dadi panas utawa cooling kang bakal terus kanggo 20 menit lan banjur wektu kanggo 2nd stage kudu wektu sing liwat tanpa termostat nelpon "Y2". Yen unit ing mode dadi panas, sapisan 2nd stagIng wiwitan, wektu 20 menit bakal nggawa panas AUX yen wektu kasebut wis liwati tanpa marem telpon pemanasan. Sawise kabeh stages wis disebut, padha bakal tetep disebut nganti thermostat kanthi marem.
3. If more than 3 consecutive “Y1” calls take place without the thermostat calling for 2nd stage ing 20 menit utawa, sadurunge 20 menit 2nd stage timer entek, ing panggilan "Y1" kaping papat, siklus pangopènan diwiwiti sing bakal nahan lan ngunci sistem dadi 2nd s.tage kanggo 5 menit kanggo njamin lenga bali menyang kompresor. Yen sistem zona udara, terminal Zone Override "D" bakal menehi energi nganti 24 volt. Kaya sing diterangake ing manual instalasi unit sampeyan, sinyal 24-volt iki bisa digunakake bebarengan karo relay isolasi sing disedhiyakake lapangan kanggo mbukak zona paling gedhe lan tahan yen dampmbukak supaya blower ora ndeleng tekanan statis dhuwur sajrone 5 menit kasebut. Siklus pangopènan ngunci telpon liya nganti rampung. Sawise siklus pangopènan, utawa yen telpon "Y2" digawe sadurunge siklus pangopènan dumadi, counter ngreset bali menyang nul. Iki ndadekake zona sistem kita loropaken amarga ngidini kanggo bener 2 stagyaiku pemanasan lan pendinginan.
4. There is an installed jumper on the field wiring terminal block marked “A” and “S”. With the jumper installed, the unit will function with an aux heat strip as normal. If the jumper is removed, the PLC goes into dual fuel mode stopping the compressor when there is a call for aux heat. Once the aux heat call completes, a 5-minute cool down timer prevents the compressor from restarting on a “Y” call until the time elapses. This allows time for the furnace to cool so hot air doesn’t cause high discharge pressure or a lockout when the compressor restarts.
5. When the thermostat is set to cooling mode, the “O” signal energizes the reversing valve and locks out the aux heat output.
6. In an effort the reduce energy consumption, the PLC turns power off to the crank case heater when the compressor runs.
7. This PLC program also allows the use of almost any heat/cool thermostat. Even if a single stage panas / kelangan mung thermostat digunakake, program PLC bakal ngontrol kabeh fungsi staging 2nd stage lan AUX Heat yen perlu.

WGxAH Tunggal lan Loro Stage Udara Dipeksa kanthi Fungsi Pemanasan Hidronik

In addition to the function and features as described for WG2A units, The PLC program for the WGxAH units allows for switching priority call from forced air to hydronic heating as well as a feature
called “Split Zone” that are installer optioned by choosing jumper settings as described below.

• A jumper is used on the field wiring terminal strip between the “R” and “AW” terminals to prioritize air heating over hydronic heating. When this jumper is removed, hydronic heating becomes the priority call.
• Split Zone is a feature which allows you the ability to heat one zone or floor with hydronic heat and another zone or floor with forced air. Split Zone is active by removing the priority call jumper across “R” and “AW” moving it across the “R” and “SZ” of the field wiring terminal block.
• While in “Split Zone” mode, the compressor unit will provided forced air heating to the air zone. When the buffer storage tank calls for heat, the compressor unit will shift to heat water. Should a call for the air zone take place while the compressor unit is heating water, the call goes directly to the aux heat source to maintain the air zone. Once the tank temperature is satisfied, the system diverts back to normal air heating with the compressor unit.
• When a hydronic heat call from the buffer tank takes place, the compressor turns off if it is running. 1 minute after that, the circulator pump starts to establish good water flow, the 3 way valve energizes and the SV1 valve de-energizes. 1 minute after that the compressor starts. Once the tank thermostat is satisfied, the compressor stops and the pump will continue to run for 30 seconds before turning off to gain any residual heat from the heat exchanger. 1 minute after the compressor stops, the 3-way valve de-energizes. 1 minute after that the compressor can restart for an air zone call. These timed cycles reduce system component wear by not having to shift under pressure or load.
• The Hydronic heating function is disabled anytime the “O’ terminal is energized placing the unit in cooling mode.

WG2AD Air Peksa kanthi Fungsi Pemanasan Banyu Domestik

Saliyane fungsi lan fitur minangka diterangake kanggo Unit WG2A minangka diterangake ing bagean pisanan saka document iki, program PLC kanggo Unit WG2AD ngidini kanggo ngoper telpon prioritas saka online dipeksa kanggo dadi panas banyu domestik.

• A jumper is used on the field wiring terminal strip between the “R” and “AW” terminals to prioritize air heating/cooling over domestic water heating. When this jumper is removed, domestic water heating becomes the priority call.
• When a water heating call from the water tank takes place, the compressor turns off if it is running. 1 minute after that, the circulator pump starts to establish good water flow, the 3 way valve energizes and the SV1 valve de-energizes. 1 minute after that the compressor starts. Once the tank thermostat is satisfied, the compressor stops and the pump will continue to run for 30 seconds before turning off to gain any residual heat from the heat exchanger. 1 minute after the compressor stops, the 3-way valve de-energizes. 1 minute after that the compressor can restart for an air zone call. These timed cycles reduce system component wear by not having to shift under pressure or load.
• An added functional PLC feature exclusive to the WG2AD model which allows water heating up 120 degrees, is the unit’s ability to maintain compressor stability by throttling the compressor load as needed to control discharge pressure.

WG1H 100% Hydronic Heated and Chilled Water Only– List of functions

1. The PLC checks that the LOW/HIGH pressure, HX Low and Discharge temperature switches are made. An open safety switch input has a 60 second delay before setting a lockout and fault signal to “X”. This is to prevent nuisance calls, especially at the beginning of the cooling season when the Earth Loops are at their coldest. “X” is set with any hard lockout condition. Turning the low voltage menyang unit kompresor mati banjur bali ing ngreset lockout anggere ngalih suhu discharge ora mbukak. Ngalih suhu discharge duwe tombol reset manual. Ngalih suhu discharge mbukak bakal tansah mbutuhake reset manual bebarengan karo vol kurangtage siklus daya. Tekanan lan HX Low temperature switch otomatis.
2. An “N” call starts the circulator pump for 30 seconds prior to the compressor to allow for full flow through the HX (heat exchanger) prior to starting the compressor. Once the call is complete, the pump will run an addition 30 seconds after the compressor stops to purge the HX of any residual heat. This occurs regardless of either a heated or chilled water call.
