HR91EE RF Thermostatic Head

Description

Honeywell HR91EE RF Thermostatic Head

for Honeywell V2000 or V320 series valves. Powered by 2 AA batteries included

Programmable electronic thermostat head for thermostatic valves, with bidirectional RF communication, integrable in EvoHome Honeywell multi-zone control systems.

Radiator valve mountable RF servomotors have been designed to provide individual room temperature control in modern heating systems where area control is desired. HR91EE uses the "fuzzy logic" control algorithm to ensure increased control accuracy. HR91EE communicates in radio frequency and receives information about the current reference temperature from the EvoTouch, the central component of the Evo Home system, and transmits the required heat and current temperature to it. HR91EE can be mounted on any conventional radiator valve.

No adapters are required for valves manufactured by Honeywell, Heimeier, Junkers and Landis & Gyr and Watts. The HR91EE adapts to the valve stroke. Adapters for mounting on Danfoss RAV valves included.

Characteristics:

anti-seizure function activated weekly
operation with 3 AAA batteries
self-adaptation to the valve stroke
simple RF connection procedure
the internal temperature sensor can be deactivated if an external RF-connected sensor is used with the EvoTouch (if the radiator is built-in or has no efficient air circulation).
Temperature regulation range: - + 5 ... + 30oC, with anti-freeze threshold at + 5oC

Sensitive element: built-in 20kΩ NTC thermistor, can be deactivated
