10. Configuration (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 three micro switches:
Dry contacts type: Isolation 3750 Vrms / 1 min, 30VDC / 0.6 A max.
Hysteresis of contacts: CO2: 100 ppm, VOC: 10% of the formaldehyde threshold equivalent, RH: 10%
of the threshold.
0/10V output is a mix of CO2, VOC and humidity (with an OR function: the most significant prevailing
over others). The speed 1 threshold corresponds to 0.68V and 5.32V threshold to speed 2. Nevertheless,
there is always a minimum of 10% ventilation so 1V.
# 1&2 Operating action contact: Normally
Open (NO) or Normally Closed (NC).
In EnOcean sensor mode: Unique
threshold selection # 1 or # 2 (# 1= NO, #
2 =NC)
# 2 Thresholds: CO2: 1250 or 1800ppm
(selectable) or 3 ppm formaldehyde
equivalent (VOCs) or 85% RH over 5
minutes. H = High / L = Low
# 1 Thresholds: CO2: 500 ppm or 900
(selectable) / 0.5 ppm formaldehyde
equivalent (VOCs) or 75% RH over 20
minutes. H = High / L = Low
