085 Ppm threshold for CO
2
relay in
HD46 models with simplified mode
enabled.
Over the whole range 800 (6)
086 Temperature relay threshold (X10)
in HD46 models with simplified
mode enabled.
Over the whole range 210 (3),(4)
(6)
087 Humidity relay threshold (X10) in
HD46 models with simplified mode
enabled.
Over the whole range 500
(3),(4)

088 Minimum possible threshold in ppm
for CO
2
relay in HD46 models with
simplified mode enabled.
Over the whole range 600
089 Minimum possible threshold (x10)
for temperature relay in HD46
models with simplified mode
enabled.
Over the whole range 150
(3),(4)
090 Minimum possible threshold (x10)
for humidity relay in HD46 models
with simplified mode enabled.
Over the whole range 200
(3),(4)
091 Minimum possible threshold in ppm
for CO
2
relay in HD46 models with
simplified mode enabled.
Over the whole range 2000
092 Maximum possible threshold (x10)
for temp. relay in HD46 models
with simplified mode enabled.
Over the whole range 250
(3),(4)
093 Maximum possible threshold (x10)
for humidity relay in HD46 models
with simplified mode enabled.
Over the whole range 700
(3),(4)
(3) The displayed value for temperature and humidity is the quantity value multiplied by 10 (decimal
point not displayed).
(4) The parameter measuring unit is the same as the respective measured quantity, set with P#006
and P#007 parameters.
(5) This parameter is for HD45 models.
(6) In HD45 models with relay, if the hardware threshold selector is in position other than 0, the relay
operates only with threshold set via hardware, A and B thresholds are not taken into account.
In HD46 models, if the simplified mode is enabled, relays operate with P#085, P#086 and P#087
thresholds. A and B thresholds are not taken into account.
