Parameter

 

Range

 

Valve thread

M 30 x 1,5 (adapter available for other types)

Ambient operating temperature

0 to 40°C, max 70% rH

Flow pipe temperature

75°C max

Transportation & storage temperature range

-10 to +45°C, max 70% rH

Max pin stroke (calibration range)

> 5 mm

Operating pin stroke (0-100 %)

2.5 mm typical

Pin Stroke Resolution (defined by EnOcean Equipment Profile A5-20-01)

Steps of 1% (smallest executable position change must be 3% from current physical position)

Adjustment speed

0.95 mm/s typical

Stall force

100 N typical

Noise level

< 30 dB(A)

RF communication interval

Default: Automatic 2/5/10 minutes
Other settings through Remote Commissioning

Activation and debug

RF communication interval

~ 10 sec
(will revert to the default 10 minutes after 10 minutes)

Antifreeze

Below 6ºC, open valve to 95%

Safe position

(following 6 consecutive communication failures)

Internal temperature controller with 21°C target value
Will revert to standard operation as soon as radio communication is online again

EnOcean EEP and operating mode

A5-20-01 (Valve Position and SetTemp)

EnOcean Remote management & Remote commissioning capability

Yes

Accuracy of internal ambient temperature sensor

+/- 0.5 ºC 

Offset of internal ambient temperature sensor

Default: Automatic offset correction
Fixed offset settings through Remote Commissioning

Energy storage

Construed for full year operation when sufficiently charged in winter season. Pre-charged, immediately ready for use if stored for up to 12 months and at a storage temperature of no more than 40ºC

Energy generation minimum requirement

90 standard heating days per year
@ >45ºC flow pipe temperature and 8h heating
@ 10minutes duty cycle and steps of 10% per cycle

Battery voltage flag

Battery voltage < 3.1 V (prefer more margin as this level is also used to reset communication interval): Set battery-low flag and reset RF communication interval to default 10 min
