The 75F Smart Stat when used to control a Heat Pump unit operates very similarly to a typical thermostat with a few added benefits for a commercial environment.
- The Smart Stat communicates through a mesh network back to the CCU (like all 75F terminal equipment) for reliable communication and remote access.
- Data streaming from the Smart Stat can be used as an immediate indicator of a mechanical issue. Meaning you should know about the issue before your tenants do.
- Programming is simple and remotely accessible. No longer do you have to go physically to the thermostat to set schedules, nor do you have to manage multiple logins. Programming user limits so you no longer have schedules changing without approval.
Wiring the Smart Stat to a Heat Pump is easy just like a standard thermostat. 75F does provide a 10k type II thermistor probe for each Smart Stat sold which is to be installed as the supply air temperature sensor. This sensor is used for alerting on poor unit health.
The Smart Stat is a single setpoint thermostat. Don't let that scare you, it is highly configurable with heating and cooling dead bands as well as a configurable hysteresis value. See the below simulation of a Smart Stat controlling a Heat Pump.
The adjustable heating and cooling dead band offer many advantages.
- Eliminate short cycling protect your unit from unnecessary wear
- Longer runtimes and higher efficiency
- Precise comfort
The Smart Stat also has 7 onboard sensors that can be viewed from your Facilisight account. Currently none of the sensors besides temperature have any impact on the function of the unit. What they do is provide insight into the space so that you have the power to take action and speak confidently to any potential issues in the building.
