INSTALLING'THE'THERMOSTAT'
There are five basic steps to installing the thermostat:
1. Turn off power to the HVAC system.
2. Determine the wiring configuration.
3. Install new thermostat, removing old thermostat and
mounting the Wall Plate if required.
4. Turn power back on to the HVAC system.
5. Configure the new thermostat.
Tools'
You may need the following tools to install the Optima S Thermostat:
• #1 Phillips or flathead screwdriver
• Drill with 3/16” bit (only if you cannot mount the thermostat using
the existing holes)
• Smartphone or camera to take picture of wiring for later
reference
• Small screwdriver to disconnect wires from old terminals
• Pencil
Page 14

!
Turn'Off'Power'to'HVAC'System'
Locate the HVAC switch or the panel breaker and turn OFF the system.
or
Determine'Wiring'Configuration'
If the Optima S Thermostat is being installed in a new system, refer to
Appendix A for the proper wiring configuration and skip to the Install
Mounting Plate section.
When replacing an existing thermostat, the goal is to replicate the
wiring of the old thermostat on the Optima S Thermostat.
• Remove the old thermostat to expose the wiring terminals.
• Take a picture of the wiring for future reference.
Page 15
Optima S Thermostat 9
!
• Note the terminals attached to each wire and attach the matching
label to the ends of the wires.
• If the terminals are unmarked on the old thermostat, you may
need to go to the furnace / air conditioner / heat pump to
determine the terminals for each wire color. Use the table
below to keep track.

Remove'Old'Thermostat'
Remove the old thermostat from the
wall, taking care not to allow the wiring
to fall inside the wall.
Install'Mounting'Plate'
Use the included wall anchors and screws to attach the Mounting Plate
to the wall, making sure the wires run through the center opening.
If there is wall space behind the old
thermostat that needs to be covered,
insert the Wall Plate between the
Mounting Plate and the wall as
shown, and mount both plates using
the same anchors and screws. The
Wall Plate can be placed vertically or
horizontally for proper coverage.

Page 17
Optima S Thermostat 11
!
If the alignment of the existing holes is horizontal, the Wall Plate can
also be used to adapt the horizontal holes to the vertically oriented
holes of the Mounting Plate. With screws, attach the Wall Plate to the
wall using the horizontal holes. Then use the Locking Pins in the
vertical holes to attach the Mounting Plate to the Wall Plate.
Attach'Wiring'
Before attaching the wires, match the
wire (using the labels) to its
corresponding terminal. Refer to the
picture of the wiring taken earlier if
necessary.
• Push the button to the right of
the terminal to be connected.
• Fully insert the desired wire into
the hole of the terminal and
release the button.
• If properly engaged, the button will remain slightly depressed
when released.

Check'the'Batteries'
The Optima S Thermostat will
automatically draw from the AC
connection (RC to C) first. If AC power is
not available, the device will
automatically switch to the internal
batteries.
Two alkaline batteries are installed in
the back of the thermostat. To activate
them, pull the Battery Tab.
The batteries will last approximately 18 months under normal usage.
When it is time to change the batteries, a low battery icon will appear
on the display.
Initial'Configuration'
As the Optima S Thermostat starts up, it will try to pair with a network
for 10 minutes if it was not previously associated with a network. When
it finds a network, times out after 10 minutes, or pairing is canceled by
the user, the thermostat will ask for the Region information and the
equipment type.

USING'THE'THERMOSTAT'HOME'SCREEN'
The Optima S Thermostat offers basic functions using the Home
Screen controls, such as changing the Set Point and turning on the fan.
To conserve energy and minimize distractions at night, the display
automatically turns off after 10 seconds of no activity by default.
Changing'the'Set'Point'Temperature'
To change the set point, simply touch the Up (+) or Down (+) button.
The ambient temperature will move to the time display area and the
current set point will be displayed in the Main Temperature display.
The Message Display will indicate which set point is being changed.
Use the Up (+) or Down (+) buttons to select the desired set point and
touch the Main Temperature display to save the new set point and
return to the Home Screen. The thermostat will also save the new set

The set point is adjusted by 1 degree for each button press when in
Fahrenheit mode and 0.5 degrees when in Celsius mode. There is a
minimum separation between the Heat and Cool set points. If the set
point being changed gets too close to the other set point, the other set
point will be adjusted to maintain the separation. The default
separation is 1.5°C / 3°F.
The set point temperature will stay at the selected value until changed
using the Home Screen buttons or by the connected smart home
system.
Holding'A'Set'Point'Temperature
If you would like to have the Optima S Thermostat ignore set point
temperature changes from the connected home system, you can place
the thermostat on Permanent Hold.
To do this, select the desired set point temperature using the Up (+) or
Down (+) button and press the Fan button while the desired set point
temperature is displayed on the Main Temperature display. The
Permanent Hold icon will appear to indicate the Permanent Hold state.
Page 23
Optima S Thermostat 17
!
To remove the Permanent Hold state, press the Up (+) or Down (+)
button on the Home Screen to display the set point temperature and
press the Fan button. The Permanent Hold icon will disappear and the
thermostat will accept set point changes from the connected home
system. The current set point will be maintained until a future change.
Changing'The'Operating'Mode
To change the operating mode of the system, simply touch the Mode
button to select between the following:
• Off – The thermostat will not call for heat or cooling.
• Cool – The thermostat will call for cooling if the room
temperature is above the Cool set point.
• Heat – The thermostat will call for heat if the room temperature
is below the Heat set point.
• Auxiliary Heat – For Heat Pump only. The thermostat will call for
heat from the auxiliary heating unit instead of the Heat Pump if
the room temperature is below the Heat set point.
• Auto Heat/Cool – The thermostat will call for heat or cooling as
required to keep the room temperature within the range set by
the Heat and Cool set points.
Page 24
18! Salus
!
Frost Protect is active by default in all the above modes, including Off
and Cool. Should the room temperature drop below the Frost Protect
set point, the thermostat will call for heat to prevent frost damage.
Turning'On'The'Fan
The Fan operates in one of two modes, Fan Auto and Fan On. In Fan
Auto, the fan will turn on when the thermostat calls for heat or cooling.
It is off otherwise. Fan On keeps the fan running continuously.
When you want the fan to be on regardless of the heating or cooling
state, press the Fan button on the home screen. The Fan Auto icon will
disappear to indicate the Fan On mode of the fan. There will be a slight
delay between selecting Fan On mode and the fan turning on
Press the Fan button again to put the fan back into Fan Auto mode,
under the control of the thermostat.
The Fan Status icon will indicate when the fan is on or off, appearing
when the fan is on.

TROUBLESHOOTING'
The thermostat does not call for heat and/or cooling.
• Check that the connector pins are straight.
• Check that the thermostat is fully seated on the mounting plate. If the
terminal connections are not fully engaged, the firmware does not
activate the relays. This prevents power surges to the HVAC system.
The heat and cooling are reversed.
• Check that the thermostat is configured properly, Heat Pump or Non
Heat Pump. If Heat Pump, Check that the O/B configuration is correct.
• Check that the wiring is correct, especially the Y and W wires. If Heat
Pump, Check that the O/B wire is correct.
The fan does not turn on.
• Check that the wiring is correct, especially the G wire.
• If oil or gas heating, make sure the furnace is working. In furnace mode
(FURNC), the fan is under furnace control to avoid a blast of cold air at
the start.
Display does not appear when low batteries are replaced.
• Press the Reset button on the bottom of the thermostat with a
straightened paper clip or pen point.
