ON
• Enthalpy Wheel at 100% speed • Wheel Entering / Leaving Air Temperature Sensors • Reduce speed based on desired leaving air temp before recirculated air • TRICOIL Pump motor OPEN • Bypass Valve to bypass heated return air, which reduces amount of warm return air to space |
If Indoors Becomes TOO COLD (aka, reduction in bypass reheat), then • CLOSE: Bypass Valve for heated return air used to warm the building • OPEN: Hot Water Valve to use the BTUs of the geothermal heat pump rejected heat of the warm water temperature to warm the building • Leaving Air Temperature Sensor on DX Coil is to adjust the variable frequency drive of the heat pump compressor to save energy. |
