PEQ Series 3 (3157100-WP) Thermostat Review

(Last Updated On: July 15, 2017)


Most smart or programmable thermostats handle all the data processing and scheduling on their own. While this is great news to someone who wants a one-time solution, it pushes the cost of programmable thermostats up to accommodate the extra logic and memory chips. Even though on board automation chips might be getting better with time, they’re still a far cry from the powerful processors you will find in home automation hubs like the Almond + controller.

The PEQ 3157100-WP thermostat is your budget thermostat that controls your electric or gas HVAC system with help from your smartphone, the web or in person when you enter the desired changes into the thermostat using a compatible home automation hub or the PEQ online control service.

Design and Appearance

The PEQ series 3 thermostats are compact sleek units with a single unicolor front. The black matte finish looks especially appealing. Since all controls are on the touchscreen, you can tap to change the mode, hold the temperature or control your fan easily without having to turn to the mobile app.

Since it is not a programmable thermostat, you cannot come up with a 7-day schedule to monitor different HVAC scenarios. Understanding this before buying the unit is very important. If you are seeking a unit that will fall into your home automation grand plan and already have an automation hub, then it is an excellent unit. If not, you will be better off buying other programmable thermostats.

After this, you can download the PEQ app available on Android or iOS and use it to monitor or program your smart hub that will in turn control all the sensors hooked up to the system. The options are endless, and the system will be as powerful as the number of sensors connected to your controller hub.

If you don’t want to spend hours programming scenes or setting down HVAC automation rules, you can subscribe to a PEQ package and use their powerful rules engine to automate your home. The PEQ subscription fee remains constant regardless of how many sensors you have in your system. Subscribe if you are willing to go all rogue and automate possible section of your home.

What if You Don’t Want the Subscription

You can always skip the PEQ home system approach and hook up the thermostat to another controller hub. The fact that the system will give you absolute control from the hub allows you to run better automation as opposed to other limited programmable thermostats whose API block out some features to remote users. One of the best controller hub options would be the Securifi Almond + controller.

PEQ Thermostat Installation and Getting Started

Installing this Open Home certified system is relatively easy – especially if you remember to label your previous thermostat wires before disconnecting it. It is a 24 VAC system that will need a common wire for continued power. If you don’t have a C-wire, you can make do with 4 AA batteries. The battery life will always depend on the batteries you purchase. Running a C-Wire will save you a lot of frustrations in future.

When installing the PEQ thermostat, ensure that:

  • You place it a good 5 ft. From the floor, direct sunlight, fireplaces or other heating and cooling places
  • Do place the thermostat near doors or windows that lead to the outside
  • Don’t install it in a damp area
  • Install it in an area with good air circulation
