Siemens REV24 Thermostat: Complete Guide
The Siemens REV24 Programmable Thermostat is an environmental regulator that allows you to achieve the ideal temperature at your desired time. Various functions are available for your comfort needs, as illustrated below. This thermostat includes a low battery indicator.
Table of Contents
This thermostat supports customized weekly programming for each day, allowing you to set it to turn on in the morning and evening on weekdays. You can use the two available temperatures to adjust the heating to your needs. Here are some example programs:
In this weekday program, the heating turns on at the start of the day (around 6:00 AM), allowing the temperature to reach about 18°C in an hour. The heating remains off until 5:00 PM. Here are other example programs:
Bonus Modes
The thermostat has special modes, including:
- Holiday Program: Interrupts heating for a set period, then resumes normal programming at its end.
- Party Program: By pressing the Party button for 3 seconds, you can set a temporary period to override the desired current temperature. At the end of the set period, the program resumes normally.
- Special Day Mode: Can be used in case of illness to override up to 3 heating periods.
Useful Tips
- It is recommended to replace the thermostat’s batteries approximately every 2 years
- Avoid using rechargeable batteries
- Recommended temperatures:
- For turning off: reduced temperature recommended at 16°C
- For turning on: comfort temperature recommended at 18°C +/- 2°C
Installation
The regulator should be mounted in the main room. It can be wall-mounted with or without an embedded box.
- Mount the unit in a location that allows easy measurement of average room temperature, away from solar radiation or cold sources.
- Avoid sources of disturbance, such as:
- Avoid mounting on metal surfaces
- Do not mount near electrical cables or electrical equipment like PCs, TVs, microwaves, etc.
- Do not mount the unit near metal walls or structural elements
- For heating systems with cast iron radiators, plan to turn on at least one hour in advance and turn off accordingly to make the most of thermal inertia.
