Frequently Asked Questions

How do I change the temperature on my Smart Touch Thermostat?

You can change the temperature at the thermostat itself or through the Grand Alarms Smart Home App. In the app, open the thermostat controls and adjust the setpoint up or down. The Smart Touch Thermostat supports remote control of setpoint and mode through the platform.

How do I change my thermostat from heat to cool?

You can switch modes from the thermostat display or in the Grand Alarms Smart Home App. The Smart Touch Thermostat supports mode changes remotely, including heating and cooling control through the app.

How do I create a schedule for my Smart Touch Thermostat?

Use the Grand Alarms Smart Home App to build a comfort schedule around your routine. The Smart Touch Thermostat supports schedules, rules, and scenes through the platform so you can automate temperature changes throughout the day.

How do I control my thermostat when I am away from home?

Open the Grand Alarms Smart Home App and adjust the thermostat remotely. You can change the setpoint, switch modes, and manage schedules from your phone or through the web portal.

How do I know if my Smart Touch Thermostat needs new batteries?

If the batteries are low, the thermostat will show a low-battery condition. The Smart Touch Thermostat uses 4 AA batteries, and the installation guide says to replace them with four new AA batteries when needed.

How do I replace the batteries in my Smart Touch Thermostat?

Pull the thermostat straight off the wall plate, remove the old batteries, insert 4 new AA batteries with the correct polarity, and press the thermostat back onto the wall plate carefully so the pins align properly.

How do I know if my Smart Touch Thermostat works with my heating and cooling system?

The Smart Touch Thermostat is designed to work with most common residential HVAC systems, including single-stage and multi-stage systems. It also supports up to 3 stages of heat and 2 stages of cooling. If you are unsure, Grand Alarms should confirm compatibility before installation.

How do I reconnect or reconfigure my Smart Touch Thermostat after a wiring change?

If your wiring has changed or the original setup was entered incorrectly, the installation guide says the thermostat can be reconfigured. Advanced configuration is available through the display settings, but HVAC-related settings should be handled carefully or by a professional.

How do I add or remove the Smart Touch Thermostat from the Z-Wave network?

From the thermostat, go into Settings, then Installer, then Network, and select Add/Remove. The guide also says you should refer to the Z-Wave controller documentation when removing devices from the network.

How do I fix my thermostat if the wiring shows as invalid?

If the thermostat says the wiring is invalid, the guide says common causes include no wires detected, no RC wire detected, Y detected without G, or O/B detected without Y. Check the wiring against the terminal guide, make sure wires are fully inserted, and then reconfigure the thermostat.

How do I fix the thermostat if heating or cooling does not turn on right away?

The Smart Touch Thermostat may insert a compressor protection delay before heating or cooling starts. The guide notes this delay is there to protect the equipment, so there can be a short wait before the system responds.

How do I change humidity or ventilation settings on the Smart Touch Thermostat?

Humidity and ventilation settings can be adjusted through the thermostat’s advanced configuration and, in some cases, through the customer website or mobile app. If those settings are not available in your account, contact your service provider.

How do I test my Smart Touch Thermostat after installation?

After setup, the guide says you should test both the thermostat and the HVAC system. It also warns not to test cooling mode during cold weather, because that can harm the compressor. Wait for mild temperatures before fully testing cooling.
