Special Controllers
EC-300
230VAC, Energy Controller for energy saving in offices
or hotel rooms. Turns off/on HVAC + lighting systems
per presence in a room via an Occupancy Sensor and
optional Contact Inputs
The EC-300 is a smart Energy Controller, which offers
substantial energy saving of Air Conditioning & Lighting
operation in hotel bedrooms, offices or conference rooms.
Since hotel bedrooms have different needs from offices
regarding occupancy changes, the EC-300 allows different
configurations for them. In both applications, presence
detection is achieved via an Infra Red Occupancy sensor; if
the IR sensor detects no presence within a certain,
configurable time, the EC will cut off electricity to HVAC &
Lighting systems. Upon detection, EC will automatically re-operate the systems. Further energy saving is achieved
by cutting off electricity to HVAC system if someone opens the window, or if set temperature exceeds the Limit Cool
or Limit Heat. For Hotels, additional Contact Input, a door switch, or other Normally Closed input is employed to
stop HVAC, Lighting or both.
Available also in 24VAC version
