Furnace Settings (con’t)
Two auxiliary inputs (AUX1 and AUX2) are provided on the communicating
gas furnace control for external control of the system (see the furnace installation
instructions for additional details). These inputs can be configured as normally
closed or normally open when used in conjunction with the AUX Common. These
inputs can be used for field accessories such as smoke detectors, freeze stats,
etc. The inputs are configured by the installer
as follows:
AUX Input #1 or 2 Congured – N.O. (Normally Open) or N.C.
(Normally Closed): setting to activate the input to the furnace control IFC (see the
furnace installation instructions).
- If Normally Open is selected, when the AUX #1 or 2 input is connected to AUX
Com by a closed switch (e.g. drain switch, freeze switch, etc.) the user selected
actions will occur.
- If Normally Closed is selected, when the AUX #1 or 2 input is disconnected to
AUX Com by an open switch the user selected actions will occur.
User Selected Action:
• Off (This is the default setting. These inputs are turned off)
• Float Switch Alarm (shutdown cooling with an active alarm)
• Shutdown (This shuts indoor and outdoor units down, no alarm)
• Shutdown Cool (In cooling mode this shuts down the outdoor unit,
no alarm)
• HP Heat Lockout (In heating mode this shuts down the outdoor unit,
no alarm)
• Furnace Heat Lockout (In heating mode this shuts down the gas furnace,
no alarm)
Filter Type – Media, Electronic Air Cleaner (EAC) or both. The filter type
selected will drive the air filter service reminder experience.
Fuel Type – Natural gas or propane.
Note: This only adjusts the EcoNet Smart Thermostat’s control settings and does not convert the
actual Gas Furnace to operate with Propane. You must use the proper orifice kit for the model
Furnace installed.
Elevation – This is the elevation at or above sea level.
Bypass Temp Limit – The maximum temperature for exiting air temperature
while the system is bypassing. If the limit is exceeded the system may shutoff and
trigger the T027_Z Supply Temp Limit Exceeded to Bypass alert.
The default limits by application are:
• Furnace 160°F - this can be adjusted down to 100°F
• Cooling 45°F
• Heat pump heating 120°F
• Heat pump with electric heat 135°F
Max Furnace Capacity – Allows reduction of the maximum blower speed.
Can be used to reduce the indoor blower airflow. This will also reduce the
operating capacity.
