10. Threshold settings (EnOcean, Modbus RS485 and
Analogical Board)
10.1.
Position the micro switches
Two dry contacts of analog board (speed 1 and 2) or RS485 & EnOcean commands operate based on
CO2, VOCs and RH parameterized thresholds by micro switches:
If the actuator is an On/Off type, the triggering thresholds are those selectable as per here above. If one
of the measures overpasses one of the thresholds, the ventilation is trigged ON. In this case, hysteresis
to stop ventilation are: CO2: 100 ppm, VOC: 10% of the threshold, RH: 5% of the threshold.
If the paired actuator is continuous, please refer to the 0-10V output manual because the algorithm is the
same one.
See
http://www.nano-sense.com/Docs/UK/E4000-NG/E4000-NG-Analog-option.pdf
The continuous command is a mix of CO2, VOC and humidity (with an OR function: the most
significant prevailing over others). Only the micro switch # 4 and 1 can set the ventilation speed. There
is always a minimum of 10% ventilation for the building health.
Logic of dry contact NO, Normally Open, Normally
Closed.
Dry contact #2 thresholds: CO2: 1500 or 2000ppm
(selectable H = High / L = Low) during more than 2
minutes or RH thr 5% over 60 seconds.
Dry contact # 1 thresholds: CO2: 700 ppm or 1200
(selectable H = High / L = Low) during more than 10
minutes or RH threshold (default 75%) over 2 minutes.
VOC thresholds for regular building or sustainable
building like BREEAM or LEED:
Dry contact #1: 300 or 1000 µg/m
3
more than 10 minutes
Dry contact #2 :1000 or 3000 µg/m
3
more than 2 minutes
No marking but similar to others:
H = Haut (High) / L = Bas (Low)
