How 75F Improves Heat Pump, Fan Coil Unit, & PTAC Energy Efficiency

Imagine a residential smart thermostat with machine learning and remote control. Apply that to commercial buildings and you get the wireless-networked  75F® Smart Stat: the world’s smartest commercial thermostat. Then combine the Smart Stat with an IoT-based Building Management System and you get an incredible combination of group controls for several HVAC systems, along with lighting and boiler and chiller plant controls for a unified, wholistic commercial BAS at half the cost of the competition.

Let's take a look at how it works. 

Manage & Control with the Smart Stat

The Smart Stat provides an integrated, in-room, wall-mounted user interface with 7 onboard sensors and thermostat zone controls for single and dual-stage HVAC equipment. The Smart Stat controls a wide range of equipment to support comfortable, energy efficient commercial buildings. The Smart Stat  can easily be used to control a heat pump unit, fan coil units, and PTACs–  and when it does, it operates similarly to a typical thermostat – plus with a few added benefits for a commercial environment. Here's why the Smart Stat works well with heat pump units and more:

  • You receive immediate alerts regarding mechanical issues with data streaming from the Smart Stat, allowing you to discover potential issues before the occupants do.

  • Like all 75F terminal equipment, the Smart Stat communicates with the Central Control Unit through a wireless mesh network for secure, reliable communication and remote access. 

  • Not only is programming easy, it's remotely accessible. There's no need to travel to the thermostat to set schedules – nor do you need to manage multiple log-ins. You can also schedule changes without approval thanks to program user limits. 

Wiring the Smart Stat to a heat pump is easy, just like a standard thermostat. 75F provides a 10k, type 2 thermistor probe for each Smart Stat sold, which is to be installed as the supply air temperature sensor. This sensor is used to detect poor unit health.
