HR91 FAQ & Setup Guide
Intro:
What is HR91?
HR91 is our new wireless radiator valve working with Evohome Wifi. It’s was
developed for homeowners that will use their Evohome unit or their mobile as the
primary way to control and monitor their heating system, instead of interacting
directly with the radiator valve.
What is different between HR91 and HR92?
HR92 allows you local temperature adjustment through the dial and direct status
check via the display. With HR91 you can directly set the temperature to a
predefined set-point of 21°C or 5°C and you can check the status of the radiator
through LED indications. Also HR92 allows you modify different parameters
including: auto window fall/rise rate, valve stroke range, temperature offset and valve
position display.
Can I activate or deactivate the open window function?
Yes you can do it from the Evohome controller, with a default duration of 30 minutes.
Can I use the child-lock feature in HR91?
Yes you can activate it from the Evohome controller.
