General Description
The Monnit ALTA thermostat is designed specifically for remote configuration and energy savings. It features an integrated motion sensor to auto detect if an area or room is occupied and can be set to enter an energy saving state when not needed. The thermostat will allow you to set a maximum and minimum temperature range for both occupied and non-occupied states. The system will auto adjust comfort levels when personnel arrive and automatically return to normal when they leave. It is also a perfect solution for public buildings such as corporate facilities or schools and churches as there are no physical buttons on the device. This prevents random adjustments by unauthorized people.
Features
• Allows for remote setting and monitoring of HVAC systems.
• Detects motion for occupied/non-occupied status.
• Prevents unauthorized adjustments or tampering.
• Configuration lockout jumper prevents changes at the hardware level.
• Full functionality and startup without a gateway (gateway is required for configuration changes and to monitor the device in iMonnit).
