Install a Programmable Thermostat Yourself Without Hassle | Illustrated Gui 2026

If you're looking to upgrade your home's heating control, a programmable thermostat (cronotermostato) is the natural evolution of the traditional manual thermostat. While a classic thermostat lets you set just one temperature for the whole house, a programmable model allows you to store daily and weekly schedules, differentiated by room. This not only boosts comfort but also helps you save on energy bills. For both types, your system must be pre-wired with a connection running from the boiler to the installation point (typically in the coldest area of the home, near the entrance, or away from heat sources). This involves two wires coming from the boiler's electronic board that control the temperature regulation. Programmable thermostats can be flush-mounted or wall-mounted and are usually battery-powered, so they rarely need to be connected to the mains. By connecting a programmable thermostat to a GSM activator, you can remotely access all the device's functions via SMS.

What You Need to Install a Programmable Thermostat

• Flush-mounted or wall-mounted programmable thermostat
• Insulated screwdriver
• Electrician's scissors
• Insulating tape
• Alkaline batteries

How to Install a Programmable Thermostat

Step 1: Remove the Old Thermostat Plate

Gently pry off the finishing plate of the old manual thermostat by inserting a medium-sized screwdriver into the two side grooves of the cover. This will expose the wiring behind it.

Step 2: Access the Connections

Unscrew the screws that fix the plate to the junction box. Before proceeding, take note of the connection references for the power cables. This step is crucial for a smooth replacement.

Step 3: Install the Fixed Part of the New Thermostat

Housing the fixed part of the programmable thermostat will occupy all three available spaces. Insert it from the front until you hear the side retaining clips click into place, ensuring a secure fit.

Step 4: Restore the Boiler Control Wire Connections

Reconnect the boiler control wires, referring to the notes you took earlier. Since the new device runs on batteries, you must isolate or remove the old power supply cables to avoid interference.

Step 5: Insert the Batteries

Before fully seating the thermostat, insert two 1.5V AA/LR6 alkaline batteries. The backlit display will show the first screen, confirming that the device is powered on.

Step 6: Final Installation

Once the thermostat is seated and powered, it will begin interacting with your heating system. The device becomes operational from the moment it receives power, so you can start programming your schedules right away.
