Frequently Asked Questions - Tybox 137+ DELTA DORE
How do I set the time and date on the Tybox 137+?
Press the Menu button, navigate to Settings, then Date/Time. Use the arrow keys to adjust and press OK to confirm.
What is the difference between Comfort and Eco modes?
Comfort mode maintains your desired room temperature (usually 19-21°C). Eco mode reduces temperature to save energy (typically 16-17°C). You can customize these setpoints in the settings.
How do I replace the batteries?
Slide off the front cover. Replace the two AA batteries with fresh ones, observing polarity. Reattach the cover. The thermostat will retain settings for a few minutes during change.
Can I use this thermostat with a hot water underfloor heating system?
Yes, the Tybox 137+ is compatible with most heating systems, including underfloor heating, provided you have a compatible Delta Dore receiver (e.g., Tyxal+). In most cases, it works with normally open (NO) or normally closed (NC) valves.
How do I reset the thermostat to factory settings?
Press and hold the On/Off and Menu buttons simultaneously for 5 seconds. The display will show 'Reset'. Confirm with OK. All settings will be lost.
Does the thermostat have a holiday mode?
Yes, the Frost Protection mode (snowflake icon) maintains a minimum temperature (approx. 5°C) to prevent freezing while you are away. You can set a duration if desired.
What is the wireless range of the Tybox 137+?
The typical range is up to 100 meters in open field. In buildings, range may be reduced to 20-30 meters depending on walls and interference.
Can I control the thermostat remotely with an app?
The Tybox 137+ itself does not have built-in Wi-Fi. However, it can be connected to a Delta Dore Tydom home automation gateway for remote control via the Tydom app.
How do I pair the thermostat with a receiver?
Put the receiver into pairing mode (see its manual). On the thermostat, go to Settings > Pairing. Press OK and follow the on-screen instructions. Successful pairing is indicated by a steady light on the receiver.
The display shows 'Err' or 'Lo'. What does that mean?
'Err' indicates a communication error between thermostat and receiver. Check that both devices are powered and within range. 'Lo' means low battery – replace batteries soon. If the problem persists, consult the troubleshooting section of the manual.
