Setting up the 700 or 800 Series

The Clock

Right out of the gate you will have to set up a few things. One thing you will want to do is set the clock. The time is not displayed on the thermostat except in the clock settings screen. People have enough clocks to pay attention to. You do, however, need to set it in the event your customer wishes to use the daily schedules or set vacation schedules.

To set the clock – Go to the menu button in the bottom left corner of the thermostat and press that. Then select settings and finally click on the clock icon. The actual setting of the time is pretty self-explanatory from there.

Electric Heat

For systems using air handlers you will also need to let the control know if you have installed electric heat in the system.When using the 800 Series thermostat with M1 equipment and the proper heater, it will self identify the heater size.

To configure electric heat – Go to the menu button, click on settings, and then go to the installer in the bottom right corner. You will need to press installer for at least 5 seconds to get into the installer settings. Once in you will select the Air Handler button. Click on none and set the system up for the appropriate electric heat airflow.

External Safeties

Many systems are equipped with external safety switches such as float switches. These need to be wired into the Aux terminals on the air handler or gas furnace. Once installed properly, they can be set up in the thermostat as to what you want to happen if the safety trips.

To configure Aux switches – Enter the menu, settings and installer. Then choose the air handler or gas furnace button. On the lower third of the next screen you will see Aux #1 Config and Aux #2 Config. To the right of that you will see N.O. This is short for Normally Open. You can also choose N.C. or normally closed switches. Float switches for instance are mostly normally closed switches so you will want to set that for N.C.

Just to the right of that you will see Off. You can touch to highlight that and use the arrows to see what choices you have. Float Switch Alarm is one of them.

M1 furnaces may be backwards.  Depending on the firmware version of thermostat you have, if it alarms when set to NC, try setting it to NO.

Example:

Let’s say you have an air handler and a condensate pump with a float switch. You would wire your float switch into the Aux wires in the low voltage wire bundle to Aux #1 and Aux C. These wires should be Orange with a Blue Strip and solid Orange. At the thermostat you would set Aux 1 for N.C. and Float switch alarm. In the event the float switch trips due to a faulty or blocked pump, the alarm would be triggered to the Smart Thermostat and ultimately the customer via the Wi-Fi app letting them know that the float switch is preventing the system from operating.

DO NOT

...attempt to break Red, Common or any of the communication bus wires with a float switch. It will only create confusion for the customer and an unsuspecting technician. Besides float switch contacts are not really rated to handle communications. They just make or break voltage.

A second float switch can be wired in series, or it can be wired to Aux 2 (grey wire) and Aux C. These Aux terminals are not outputs of any sort. They are simply interruptible safety circuits.

A note of caution. A float switch trip will shut down the outdoor unit but it will not shut down a condensing gas furnace or a system with a humidifier. If you are trying to protect from water with one of these, rather than choose Float Switch Alarm, select Shutdown System Alarm instead.
