The Arzel Zoning GTPro offers customized comfort control while maximizing the efficiency of geothermal systems. It provides built-in controls to measure several different staging parameters, allowing for more precise monitoring to save time, money and energy to operate. The GTPro can be installed on residential and light commercial retrofit and new construction zoning applications.

A new sensor enables contractors to monitor the ground loop temperature ensuring proper function of the system. The loop monitoring allows for more aggressive staging when the loop temperature starts to reach a critical point. The system will stage up based on the temperature of the ground loop, keeping it at an acceptable level for maximum efficiency.

With its sophisticated software, contractors are able to customize the staging of the equipment to maximize the system's performance. The GTPro can stage the equipment based on leaving air temperature, time or zone weight. Website configuration allows contractors to select the parameters they would like to use and interlock them to ensure the unit only stages when required.

1. Ground loop temperature sensor
2. Outdoor air temperature sensor
3. Leaving air temperature sensor
4. Programmable low voltage auxiliary relay
5. USB port for simple configuration and data download

What is the third sensor on the GTPro system used to control?

The third sensor is a temperature sensor which can be assigned for multiple uses but is intended for loop temperature monitoring. 

What can I gain from monitoring loop temperature?  

You are now able to make staging decisions based on loop temp and your jobs needs.

It looks similar to the HeatPump Pro, what’s different ?  

The GTPro not only has the addition of the third sensor but offers far more programing options to allow you to have more control over how you want the staging to behave whether it be based on time, loop temp or a combination of both.
