INITIALIZATION
When power is applied to the Thermostat the display will cycle through an initialization sequence where it performs a display test and displays the firmware version. If it was not previously associated with a network, it will display JOining… 10 as it attempts to join a network. The number will count down from 10 minutes to 0.
When it either finds a network, times out, or pairing is canceled by the user, the thermostat will default to the setting HVAC EQPT TYP.
If there is no button activity for 30 seconds, the display will revert to the Home screen. If the thermostat had previously joined a network, it will default to the Home screen. Once initialization is complete, the Optima S is ready for use, or to be configured for the intended application. The Optima S may be configured manually through the keypad, or by using the SALUS Smart Home App. To use the desktop App go to https://us.salusconnect.io/login

To lock or unlock the selected functions (see settings LCK-XXX) press the + and – buttons for 3 seconds. The buttons for the selected function will disappear and appear as the function is locked and unlocked.
Schedule Function
The Optima S includes a flexible programmable schedule to vary set points based on time of day to reduce energy when there is an opportunity to relax the comfort level. While the schedule can be set using the keypad, it is more efficient to use the App. There are 5 schedule modes, each having up to 6 schedule intervals. Each Interval has a Start Time and the ability to set heating and/or cooling set points depending on the equipment type. The 5 modes are:
| WKDY/WKND | This is a 5+ 2 schedule with M/T/W/T/F with one schedule S/S another. |
| WEEKLY | With this schedule, every day uses the same Interval settings. |
| SCHD OFF | This ‘Permanent Hold’ mode turns the schedule Off and set points are set using the keypad or App. |
| WKDY/SA/S | This is a 5 + 1 + 1 schedule with M/T/W/T/F with one schedule Sat and Sun each with their own. |
| DAILY | This schedule mode each day is configured with its own schedule intervals. |
To select the Schedule mode, press the ! button
Tap the Settings button to edit the Schedule Interval 1
Continue to edit the Interval #, Time and Set Point(s) for each of the Intervals desired by advancing the Interval and editing the Time and Temperature. For applications where there is both heating and cooling, once you have set the heat set point, tap the mode button so the cooling icon s If you wish to skip an Interval (ex 4 intervals: Sleep, Wake, Leave, Return) allow the Time setting for unwanted intervals to be blank (Time = –:– and Temperature = – -). When using a Daily, WKDY/WKND, or WKDY/SA/S schedule, to select the alternate periods, with the Interval # flashing continue to tap the + or – buttons to step through the intervals for each; Day, WKDY & WKND, and WKDY, SA and S
Temporary Hold
The thermostat may be placed in a temporary hold state which will temporarily override the schedule settings until the next interval time is reached. To temporarily override the scheduled set point, simply increase (+) or decrease (-) set point. When the next interval time occurs, the thermostat will resume its programmed schedule.
Permanent Hold
To permanently override the schedule, you must turn the schedule Off either through the thermostat menu (TYPE-SCHD OFF), or by using the App. When the schedule is Off the Permanent Hold icon will appear on the thermostat display. The current set point will be maintained until a future change is made, or The Permanent Hold is turned Off by selecting a Schedule mode.
Pairing Optima S with SS909ZB Temperature Sensor
When the thermostat is located where it may not read the optimum temperature for the comfort zone, a remote wireless sensor (SS909ZB) may be paired with the thermostat and the ambient temperature of the remote sensor will be used for control.
