Friedrich EMWRT1 Energy Management Thermostats for the hospitality industry
deliver unprecedented energy savings without compromising guest comfort.
Integrated occupancy sensor uses a combination of motion and thermal sensing
technologies for accurate occupancy detection. Reliable occupancy detection
allows saving energy when rooms are unoccupied.
Energy saving presets eliminate the guesswork and make it easy to adjust the
energy saving settings. (Patent Pending)
Fully congurable energy saving settings allow customizing the thermostat
energy saving settings to t any situation.
Large buttons with international symbols make it easy to adjust the temperature
in ±1° °F or °C and control the fan speed.
Comprehensive conguration options ensure full compatibility with virtually
any existing or emerging hospitality HVAC system with up to 2 heat and 1 cool
stages.
Built-in wireless mesh-networking enables optional remote management. For
installation of a networking thermostat with remote management, refer to the
“Network Installation” manual.
