ECO-HOT/LT radiator valve



€98.00 Excl. Tax

The motorized ECO-HOT/LT valve is a simplified version of ECO-HOT reserved for private accomodation. It controls the radiator and is powered by a non-rechargeable battery with a lifespan of +/- 10 years.

ECO-HOT/LT valves communicate on the same radio frequency and synchronization and configuration are automatic with ECO-REG/LT.

ECO-HOT/LT is compatible with any type of valve body. You just place an appropriate adapter provided in the kit.

ECO-HOT/LT has a modern design without any manual adjustment. Its rounded shape is elegant and prevents vandalism as the housing is attached with a security lock.

You can install up to 4 ECO-HOT/LT valves per room.


The module has the following characteristics:

  • Wireless transmission-reception over a range of 30 m
  • Adapter for all valve bodies
  • Radiator opening or closing order reception
  • The internal battery has a lifespan of about 10 years
  • 2-year SYREG warranty on hardware
  • Maximum 4 ECO-HOT/LT per room and 64 per building
  • Automatic addressing and synchronization with ECO-REG/LT
  • Sending operating statistics to ECO-REG/LT
  • No adjustment on the valve (anti-vandalism)

Dimensions Eco-Hot

How to know whether the ECO-HOT/LT valve is compatible with the radiator?

You fix the corresponding adapter piece to the valve body. This is provided in the mounting kit and the manual gives the instructions.

How to change the opening and closing of the radiator?

By increasing the setpoint on the ECO-REG/LT regulator or ECO-MANAGER/HOME software with respect to the measured temperature.
NB, you have to exceed the ambient temperature by 0.6 ° C to warm.

Am I notified if the battery is flat?

Yes, the LCD display shows "Batra" and the ECO-MANAGER/HOME software displays a heart-shaped icon.
The lifespan of the battery is +/- 10 years and SYREG guarantees 5 years.
It is important to remove the battery if the ECO-HOT/LT module is not in connection with an ECO-REG/LT, otherwise it will discharge unnecessarily.

How to program an ECO-HOT valve?

It's simple, once the ECO-REG/LT regulator requests liaison with ECO-HOT/LT, you push the "config" button. Addressing is automatic.

Will the piston not risk to block?

On the contrary, ECO-HOT/LT continuously monitors whether the piston operates at least once per day. Otherwise, degumming is automatic every 24 hours. This process avoids to block the valve body piston.

Should we replace the valve body piston when installing ECO-HOT/LT?

For correct use, it is advisable to replace your radiators' valve body pistons. The reason is simple : in order to eliminate leaks in a hydraulic installation, installers often inject a sealant in the heating system. This becomes encrusted throughout and reduces the travel performance of the valve body. SYREG warranty does not cover valve body operation.
