Frequently Asked Questions - HmIP-eTRV-C Homematic IP
How do I install the Homematic IP HmIP-eTRV-C thermostat?
Remove the old manual thermostat, screw the adapter onto the valve, then attach the HmIP-eTRV-C and tighten the ring. Insert batteries and follow the pairing procedure in the app.
How do I pair the thermostat with the Homematic IP access point?
Open the Homematic IP app, go to 'Add Device', scan the QR code on the device, then press the pairing button on the thermostat for 3 seconds. The LED will flash green during pairing.
What type of batteries does the HmIP-eTRV-C require?
It uses 2 AA alkaline batteries (1.5 V). Rechargeable batteries (NiMH) are also compatible but may reduce battery life.
How long do the batteries last?
Battery life is typically up to 2 years, depending on frequency of valve movements and wireless communication.
Can I use the thermostat without the Homematic IP access point?
No, the HmIP-eTRV-C requires a Homematic IP access point (or a compatible central unit) to operate and be controlled via the app or other smart functions.
How do I set a weekly heating schedule?
In the Homematic IP app, select the thermostat, go to 'Schedule' and set desired temperatures for different times of day and days of the week. The device will automatically follow the program.
What does the window open detection do?
The thermostat detects a sudden temperature drop (e.g., when a window is opened) and temporarily shuts off the heating to save energy. It resumes normal operation after 30 minutes or when the window is closed.
How do I enable child lock?
Press and hold the 'boost' and 'info' buttons simultaneously for 3 seconds until 'CL' appears on the display. Repeat to unlock.
What does the valve protection function do?
To prevent the valve from sticking, the thermostat automatically opens and closes the valve fully once a week (usually on Wednesday at noon) for 2 minutes.
How do I clean the thermostat?
Use a soft, dry cloth to wipe the housing. Do not use water, cleaning agents, or solvents, as they may damage the electronics.
