Night Occupancy Mode

Verdant’s Night Occupancy feature is designed to ensure comfort for sleeping occupants. 

Despite the thermostat’s passive infrared motion sensor (PIR) scanning its environment for the presence of motion and/or body heat, sleeping occupants can present a challenge to even the most sensitive occupancy sensor because they,  

  • a) May not move for long periods of time while asleep
  • b) May not generate any measurable body heat while under blankets 

While other competing guestroom energy management systems attempt to resolve this challenge using additional hardware such as door switches or ambient light sensors, both can be fallible and prone to setting back temperature on sleeping occupants. 

Verdant’s Night Occupancy feature allows users to configure a time-period during the day where gaps in occupancy according to the thermostat’s sensor are ignored. In practical terms, hotel operators will often enable this feature between 8pm-8am, thereby allowing the guest’s preferred setpoint to be maintained during sleeping hours. 

It’s important to note that this feature is completely customizable, as there are many situations where “sleeping hours” may not be at night, such as pilots in airport hotels, etc.

Dynamic Intelligent Recovery

Verdant’s Dynamic Intelligent Recovery feature is designed to maximize energy savings during unoccupied periods, while ensuring the comfort of occupants. 

This system feature is comprised of several settings configured by the building operator: 

[ /]

Min & Max Setback limits

The temperature threshold (in degrees) upon which the thermostat activates heating or cooling in an unoccupied room.

9

Humidity Control

The threshold (in percentage) at which the air conditioner will activate fan and air conditioning to mitigate humidity in a room.

9

Recovery Time

The maximum amount of time allowed (in minutes) to reach the occupants preferred setpoint upon detecting occupancy in a room. 

Verdant thermostats are constantly measuring the slew rate of the HVAC unit – the amount of time required by the HVAC unit to heat or cool the room be a single degree. 

With this information, the thermostat determines the maximum amount of temperature setback possible in each unique unoccupied room in order to respect the recovery time setting.
