The EasyTouch 357 model thermostat was designed to replace certain Dometic™ multi-zone capable thermostats. Original thermostats replaced by this model are a five-button configuration with a display alongside the buttons. If your thermostat is not of this style, please contact Micro-Air https://www.micro-air.com/SupportRequest to verify the thermostat you received is correct for your application.
Mounting the thermostat Step 1: Locate the mounting buttons horizontally across the hole with the smaller diameter against the wall. Step 4: Remove mounting tab before mounting on the wall. Step 2: Screw in one screw and level the buttons so the display will be straight when installed. Step 5: Aligning the buttons with the holes in the back of the display. Press the display against the wall and gently slide the display down to lock it in place.
Initial setup instructions Available modes Switches on the control boards typically located in the air conditioners are used to configure the system. These switches determine if the system has a furnace, heat pump, generator or other features. Operating modes available will reflect the setting of these switches. No thermostat setup is required. Connecting remotely This thermostat may be operated remotely using either Bluetooth or WIFI. Apps may be loaded from the Google Play store or Apple App store.
Operating the thermostat Main screen 1. Inside temperature shows the ambient temperature of the room. 2. WIFI indicator shows the state of the WIFI connection. Green indicates WIFI is connected properly, Red indicates connection to router only, bars indicate signal strength, and no symbol indicates no connection. 3. Raise and lower the temperature set point using the red and blue arrows. 4. Use the power button to turn the system on or off. Button is red for off and green for on. 5.
6. Pressing the fan icon selects between manual (always on) fan speeds and automatic fan speeds. Automatic will turn the fan off after the heating or cooling cycle is completed. See table 3 for available fan speeds.

Gas Heat Override This function is handled by the control board and not the thermostat. It will activate when the outside temperature falls below the minimum heat pump operating temperature. Smart device application only features Reset device This Bluetooth only feature allows resetting the display just as if you removed and restored power. Calibrate Touchscreen It is normally not necessary to recalibrate the touchscreen.
Appendix A: Installation Troubleshooting The most common problem is not knowing the thermostat operation. If the system is running a heating or cooling cycle, the set point will turn red for heating and blue for cooling. When the thermostat turns white, the heat pump, heat strip and furnace should all be off. The fan may continue to run for a while after the cycle completes. If a fan is left in a manual mode, it will not shut off.
Appendix C: Connecting remotely First connection steps 1. This thermostat uses BLE which is a special implementation of Bluetooth. It is not necessary to “Pair” the thermostat with the phone but an account must be created for operation. 2. Start the app on your smart device. The app will open and if you have not entered your account information, it will ask you to create an account. Enter your name, email and a password at the prompts. The system will send a confirmation email to your inbox.
