Standard System Wiring

Heat Pump Wiring

* If you have a terminal marked “B” with a brown wire attached to it, that means you have a changeover (C/O) with heating type heat pump system. Be sure to set the change over type in the Installer Settings menu to C/O Type: w/Heat. Otherwise leave it set to w/Cool.

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.

System Status Indicators

When the main thermostat screen is displayed, the on-screen labels indicate the following.

Schedules

Schedules is an optional menu item. It will only show up in the menu list if “Schedules” is enabled in the Installer settings for the thermostat. Provides for local schedule control. The Schedules Screen allows you to review and set the setback schedule for the thermostat. The thermostat has a 4 x 7 schedule. Four times a day can be selected for changes to the heating and cooling setpoints. Each day of the week can have a different schedule. Groups of days can be copied with the same schedule. When the thermostat is set to “Run” mode, the schedule will be executed daily, with the setpoints being changed as per that days schedule stored in the thermostat. “Hold” mode stops schedule operation and holds the current setpoints until changed manually or by network commands.

...

The Schedules Screen gives you the option of setting a custom setback schedule or to load one of two preset schedules.

Menu Options

• Heat and Cool: You can change the individual day/hour and setpoints for the Heating and Cooling schedule by selecting this menu item.

...

Once registered at www.sitesage.net the name given to the thermostat in the SiteSage software appears at the top of the thermostat on the home screen.

Thermostat Operation

Minimum Run Time (MRT)

The thermostat has a Minimum Run Time after the start of any heating or cooling call.

...

Note: The MRT status is shown in the thermostat System Status on-screen labels.

Minimum Off Time (MOT)

The thermostat has a Minimum Off Time after any heating or cooling call is finished. This delay prevents rapid heating/cooling cycles and also provides “short cycle protection” for compressor calls. This delay may be noticeable when you change a setpoint and it does not respond immediately due to another call that has recently completed and the MOT delay timer is preventing the system from restarting. The MOT delay time can be adjusted in the Installer Settings menu of the thermostat. There is a minimum of 5 minutes delay to assure compressor protection.

...

Note: The MOT status is shown in the thermostat System Status on-screen labels.

Remote Sensors

The thermostat has two remote temperature sensor inputs.
