Savant SST-W100 User manual

The Savant Wireless Thermostat (SST-W100) is a Wi-Fi enabled wireless digital thermostat
designed to control Heating, Ventilation and Air Conditioning (HVAC) systems which
communicate wirelessly over Wi-Fi to a Savant System. The SST-W100 is designed to integrate
seamlessly into a Savant controlled environment.

To set the HVAC system type, go to the Main Menu Thermostat Info screen
and press and hold the Setup button.
1. Type. Set the HVAC System Type: set to Gas/Elec
2. Fan Type. Set the HVAC Fan Type:
Set to Gas for typical gas furnace (fan is controlled by the furnace)
Set to Elec for electric heat (fan call with heat call)
3. 2nd Stage Heat. Enable second stage heating outputs
If you have a single stage heating system, leave this set to N
If you have a 2 stage heating system, set to Yto enable.
4. 2nd Stage Cool. Enable second stage cooling outputs
If you have a single stage cooling system, leave this set to N.
If you have a two stage cooling system, set to Yto enable.
Default Setup:

Heat Pump HVAC System Wiring
Thermostat Setup:
Heat Pump HVAC Systems
To set the HVAC system type, go to the Main Menu
Thermostat Info screen and press and hold the Setup button.
1. Type. Set the HVAC System Type: set to Heat Pump
2. C/O type. Change Over (reversing) Valve Type. Heat pumps change from heating to cooling by reversing operation.

Check your system information to be sure and note the color of original thermostat wire and the terminal it was connected to.
No matter what the old stat connection was (O or B), connect the wire to the thermostats W2/O terminal.
The setting of the C/O Type will set the correct system operation.
For change over with cool systems (Orange wire, O terminal): set C/O type to w/cool (most common and default setting)
For change over with heat systems (Brown wire, B terminal): set C/O type to w/heat
3. 2nd Stage Heat. Enable second stage heating outputs
If you have a single stage heating system, leave this set to N
If you have a 2 stage heating system, set to Yto enable.
4. Aux Heat (HP). If you have auxiliary heat strips, set this to Y to enable.
5. 2nd Stage Cool. Enable second stage cooling outputs
If you have a single stage cooling system, leave this set to N.
If you have a two stage cooling system, set to Yto enable.
Note! If you get heating when you
expected cooling, change the C/O
type to the opposite setting.
