TAUA: 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.

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 na'o le tu'uina atu o le faiga o le avanoa e toe fa'aleleia ai a'o le'i tu'uina se loka malo i fafo. O le mea lea e taofia ai le faʻalavelave telefoni, aemaise lava i le amataga o le tau malulu pe a sili atu le malulu o Earth Loops. "X" ua seti i so'o se tulaga malo loka i fafo. Liliu le maualalo voltagu i le vaega compressor tape ona toe i luga toe setiina le loka i le umi lava e le tatalaina le ki o le vevela. O le su'ega o le vevela o lo'o i ai le ki o le toe setiina o le tusi lesona. O se suiga o le vevela o lo'o tatala e mana'omia i taimi uma se seti tusi fa'atasi ma se vol maualalotagu taamiloga malosi. E otometi lava suiga o omiga.
2. A “Y1” call starts 1st stagu fa'amafanafana po'o le fa'alili lea o le a fa'aauau mo le 20 minute ona fa'asolosolo ai lea ile 2nd stage tatau ona alu lena taimi e aunoa ma le fa'amalo e ta'ua “Y2”. Afai o le iunite o loʻo i totonu o le faʻamafanafanaina, tasi le 2nd stage amata, o le 20-minute timer o le a aumaia le vevela AUX pe a uma lena taimi e aunoa ma le faamalieina o le valaau faʻamafanafana. A uma loa stagua vala'au, o le a vala'au pea se'ia fa'amalie atoatoa le fa'amalo.
3. If more than 3 consecutive “Y1” calls take place without the thermostat calling for 2nd stagi totonu ole 20 minute po'o, a'o le'i o'o ile 20 minute lona lua stagua uma le taimi, i le valaau lona fa "Y1", ua amata se taamilosaga o le tausiga o le a taofia ma lokaina le faiga i le 2nd stage mo le 5 minute e faʻamautinoa ai le toe foʻi atu o le suauu i le compressor. Afai e fa'asona le ea, o le sone Override terminal "D" o le a fa'amalosia i le 24 volts. E pei ona fa'amatalaina i lau tusi fa'apipi'i iunite, e mafai ona fa'aogaina lenei fa'ailo 24-volt fa'atasi ma se fa'alava tu'ufua e tu'uina atu e vala'au e tatala le sone tele ma taofi le d.amptatala ina ia aua ne'i iloa atu e le fa'a'a'u le mamafa maualuga i le 5 minute. O le taamilosaga o le tausiga e loka ai soʻo se isi valaau seia maeʻa. A maeʻa le taamilosaga o le tausiga, pe afai e faia se valaau "Y2" aʻo leʻi faia le taamilosaga o le tausiga, e toe foʻi le fata i le zero. O le mea lea e faauo ai la matou sone fa'aoga aua e mafai ai mo le moni 2 stage fa'amafanafana ma fa'alili.
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 na'o le vevela/malili e fa'aaogaina, ole polokalame PLC ole a pulea uma galuega stagi le 2nd stage ma le AUX Heat pe a manaʻomia.

WGxAH Nofofua ma Lua Stagu Fa'amalosi Ea fa'atasi ai ma le fa'avevela o le vai

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 Ea Fa'amalosi fa'atasi ma le Fa'avevela Suavai Fale

I le faaopoopo atu i le galuega ma foliga e pei ona faamatalaina mo iunite WG2A e pei ona faamatalaina i le vaega muamua o lenei pepa, o le polokalame PLC mo iunite WG2AD e mafai ai ona suia le valaau faamuamua mai le ea faamalosi i le faamafanafanaina o vai i totonu o aiga.

• 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 voltagu i le vaega compressor tape ona toe i luga toe setiina le loka i le umi lava e le tatalaina le ki o le vevela. O le su'ega o le vevela o lo'o i ai le ki o le toe setiina o le tusi lesona. O se suiga o le vevela o lo'o tatala e mana'omia i taimi uma se seti tusi fa'atasi ma se vol maualalotagu taamiloga malosi. O le mamafa ma le HX Low temperature switch e otometi.
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.
