Installation Setup

Before operating the system, the HVAC System Type must be setup in the Installer Settings/System Settings/Mechanical Settings Menu!

Default Settings: The HVAC System Type is default set for a Gas/Electric system with Gas Heat Fan type. If this matches the HVACsystem the thermostat is connected to, then no further setup is required.

If the HVAC system has Electric heat or is a Heat Pump system, then the Mechanical Settings must be changed to match. Go to the Installer Settings Menu to complete the HVAC setup.

HVAC System Setup

In the Installer Settings main menu, us the down arrow button to scroll down to the System Settings menu item and press Select.

HVAC Setup Settings

Set these settings to match the HVAC system the thermostat is connected to.

Installer Settings Summary

Connection to Mi-Wi Network

This thermostat is designed to connect to the SiteSage Gateway using the Mi-Wi wireless
protocol. The Gateway will automatically detect a thermostat and initiate the connection.

It is critical that the MAC address of the thermostat is mapped to the name of the zone served by the thermostat. The Thermostat MAC address can be found in the Mi-Wi Network menu option (the last
one in the list of options shown when the Menu Button is selected.

Operation Guide Model TM46 SiteSage Thermostat

If the System Mode is OFF, pressing either the Up or Down buttons will take you to the System Mode screen. You must first set an operating mode before you can set or change the setpoint.

To change the Heat Setpoint you must be in the Heating mode, to change the Cool Setpoint you must be in the Cooling mode. If you are in Auto mode, the mode of the last system call will be the setpoint screen displayed.

Setpoint Push: Note that you cannot lower the cooling setpoint below the heating setpoint. The thermostat will “push” the heating setpoint lower if you try to lower the cooling setpoint below the heating setpoint. It maintains a 3 degree separation between the heating and cooling setpoint. The same is true for raising the heating setpoint above the cooling setpoint. Again the thermostat will “push” the cooling setpoint up to maintain the 3 degree separation.

Setting the System Mode: Off, Heat, Cool, Auto

System Modes

• OFF: System is off. No heating or cooling will come on. If system was on, it will turn off immediately.

• HEATING: Only heating will occur.

• COOLING: Only cooling will occur.

• AUTO: Heating or cooling will come on according to the heating and cooling setpoints. The system will automatically switch between heating and cooling modes as needed to maintain the setpoints.

Special Heat Pump Mode: Emergency Heat

• EHEAT: An additional system mode, “EHEAT” for Emergency Heat will be displayed if the HVAC system type is set to Heat Pump. If there is a compressor failure with the Heat Pump system, setting the mode to EHEAT will allow the supplemental Aux heat to come on first whenever there is a call for heating. It also disables the compressor output to prevent further damage to the HVAC system.

Setting Fan Mode and System Status Indicators

• AUTO FAN: Fan automatically operated by the HVAC system.

• FAN ON: Manual Fan mode. Fan stays on until mode is changed back to Auto.

Optional Fan Mode

Fan Cycler. If the Fan Cycler feature is enabled in the Installer Setup, the additional fan mode “Cycle” will be shown in the Fan Mode menu. This mode cycles the fan on and off continuously for fresh air ventilation according to the settings in the Installer Setup.
