ESi 4 Series Wired Programmable Thermostat with OpenTherm - ESRTP4+ Overview
The ESi 4 Series ESRTP4+ programmable thermostat features OpenTherm communication technology, which can send and receive detailed data from the connected boiler, such as temperature settings, boiler status, error codes and system diagnostics.
OpenTherm also allows the thermostat to adjust the heating system precisely for more efficient heating control and energy savings (up to 15% savings on your gas use), and it can even modulate the heating base on your home's requirements, helping to prevent overheating and reduce your energy consumption.
Digital Display
This thermostat includes a digital display for easy reading at a glance, with four buttons that allow you to program the thermostat, see/adjust settings and select your desired temperature.
Programmable Functions and Holiday Mode
With the ESi 4 Series ESRTP4 thermostat, you can set specific temperature schedules for different times of the day or week, with the option of 7-day, 5/2-day or 24-hour programming.
This helps to give you more control over your home's temperature, maintaining comfort and helping to save energy so you're not heating your home when you're not around.
In fact, this thermostat also features Holiday mode to ensure you're not heating your home when you're on holiday without having to adjust your current settings. So when you return home, the programs configure as usual.
Landlord Service Reminder
With a built-in landlord service reminder, this thermostat will notify or reminder the landlord that the thermostat is due for service.
This reminder ensures the thermostat and heating system are properly services and maintained, and it can help prevent potential breakdowns.
