It’s summer — and for many, that means packing bags, locking the door, and heading off for a well-deserved break. But what happens to your home’s comfort and energy bills while you’re away?
With the Tongyi R290 air-to-water heat pump, you don’t have to worry. Thanks to its Holiday Mode feature, your home stays safe and efficient, and you return to the perfect indoor climate.
What is Holiday Mode?
Tongyi Heat Pump Holiday Mode is a smart operating setting that allows you to reduce energy consumption while you are away, without completely shutting down your system. Instead of maintaining your usual comfort temperature, the heat pump keeps the indoor temperature at an economical, pre-set level — preventing excessive energy use while avoiding issues such as dampness or frost in colder months.
When your holiday ends, the unit automatically returns to your preferred settings on the date and time you choose. This means you walk into a home that’s already comfortable — whether you need cool air after a hot August drive or cozy warmth after a winter trip.

Why it’s perfect for August
August is peak travel season. Many homes are left empty for days or even weeks, and cooling or heating them as if they were occupied wastes energy. With Holiday Mode, you:
- Save energy while you’re away
- Avoid unnecessary wear on your system
- Enjoy comfort immediately upon return
- Control everything remotely via the built-in IoT system
How to activate it
On the Tongyi R290 heat pump, Holiday Mode can be set directly from the user interface or remotely via your smartphone app. Simply select the start and end dates of your absence, and the system takes care of the rest.
A smart step toward sustainable living
By using Holiday Mode, you’re not just making your life easier — you’re also helping the planet. Lowering unnecessary energy consumption reduces your carbon footprint, and with the R290 refrigerant’s low GWP (Global Warming Potential), your heat pump is already a forward-thinking choice for the environment.
