HVAC Troubleshooting
Symptom: Homeowner would like to see the energy use of their heating & air conditioning system daily, weekly and monthly so they can manage their bill.

This is easily done with Venstar's new T5800 (residential) or model number T6800 (commercial) thermostats. You will need a T5800 or T6800 thermostat, a Wi-Fi Key model ACC0454 and a 10K supply air temperature sensor model ACCDSEN. The supply air sensor is usually easier to run than an outdoor sensor. Just use the existing thermostat wires if you have enough (if not you can use an Add-A-Wire model ACC0410 to add more wires) that run to the control board on the furnace, fan coil or package unit. Then a short run of wires from the thermostat wires at the control board to the supply duct is necessary. Of course the customer must have an open Wi-Fi router close by and the password for the Wi-Fi router to connect the thermostat to the internet.

T5800/T6800 ColorTouch thermostats give you all kinds of abilities. You and/or the customer can and change the room temperatures from anywhere in the world with your smart phone or computer. You can set the thermostat to send you an e-mail if the temperature in the house/office gets above or below a temperature you set. At anytime you can monitor the 3 day weather forecast at the house or business. You can see the high and low temperatures for outside sensor, high and low for the inside sensor and you can even troubleshoot the HVAC system to make sure everything is working correctly by monitoring the supply air sensor.

These thermostats can also send e-mail alerts to your iPhone and/or computer. They can send a service alert when it is time to change filters, UV lights, upgrade firmware or simply send an alert when is time for the annually preventative maintenance. You can also send to the thermostat any message you want to be displayed on the thermostat screen such as "The monitoring system on your AC system indicates your system is not running efficiency and may indicate a pending failure. Please call 949-888-2222 to schedule a service call".

When it is time to change a filter, time for maintenance, or the homeowner just wants to know who to call for service, this is the screen that pops up on the display.

You can easily enter the text for this screen directly on the thermostat. If you want to add the company's logo or picture to this screen, ColorTouch Assistant software makes that easy to do as well.
