1. General description
The regulators are designed for online measurement of temperature (°C or °F), relative humidity
and carbon dioxide concentration of air without aggressive ingredients. Measured temperature and
relative humidity are recomputed to following humidity expression: dew point temperature, absolute
humidity, specific humidity, mixing ratio and specific enthalpy.

The device is equipped with two relay outputs for alarming or controlling of external devices. It is
possible to assign any input value to each relay, to set comparing limit, delay, hysteresis and acoustic
alarm.
Measured and computed values are optionally shown on dual line LCD display. If there are two
values displayed at one LCD line, they are periodically switched between both readings with period
of 4 seconds. Display can be switched OFF totally too. On the left LCD side there are placed three
LEDs for CO

zone level indication.
2. Regulator mounting and connection
Regulators are designed for wall mounting. Device must be mounted on the plane surface to
prevent its deformation. Mounting holes and connection terminals are accessible after demounting of
four screws in the corners of the box and removing the lid. There is recommended to use screws with
half round head with cross-recessed screw ST 3.9 (DIN 7981). Unpack external probe for measuring
the concentration of CO2 and connect to the device.
Lace the lead-in cable with outer diameter of 3 to 6.5 mm through the glands at the case wall and
connect them according schematic below. Terminals are self-clamping and can be opened by
a suitable screwdriver. For the opening, insert
the screwdriver to smaller terminal hole and
lever by him. Do not forget to tighten glands
and case lid with inserted packing after cables
connecting. Insert attached plug into unused
cable glands too. Do not connect the regulator
under voltage.
It is not recommended to use the H6020
regulator for long time under condensation
conditions. It could be the cause of water steam
condensation inside the sensor’s cover into
water phase. This liquid phase stays inside
sensor’s cover and can’t escape from the cover
easily. It can dramatically increase response
time to relative humidity change. If water
condensation occurs for longer time it can cause
sensor damage. Similar effect can occur under
water aerosol conditions.
Electrical system (wiring) may be done only by a worker with required qualification by rules in
operation.
