Integrated electrical pre-heater and/or post heater detailed selection can be provided.
The unit can be optionally fitted with an electrical pre-heater manufac-

tured with open coil heating elements and galvanized casing.
The heater is complete with fully modulating SCR (Silicon Controlled

Rectifier) control (0-10V) and 2 stages of overheat protection (automat-
ic and manual reset) all integrated on the unit’s control logic.
The SCR control provides accurate, supply air temperature regulation.

The heat output is precisely controlled from 0 to 100% by using the unit
in-built temperature sensors or a space temperature sensor.
The electrical pre-heater is recommended when there is the need to

protect the plate heat exchanger from freezing under low ambient con-
ditions and to avoid dead times on the unit operation due to shut down
of the fans for defrost routine.
The electrical post heater is recommended where no hot water supply

is available on site and there is need for top-up heating of the supply
air.
Integrated LPHW after heater or changeover coil

The unit can be supplied with an integrated water heater battery operat-
ing with LPHW to provide supply air top up heating.
Where cooling is also required a changeover water coil can be provid-

ed operating with either chilled or heated water by a common water
circuit depending on the seasonal requirements.
The coils are manufactured with aluminum fins, copper tubes and
assembled on a corrosion resistant galvanized casing.
Maximum operating pressure 1.6 Mpa, 110°C.
The heating output is automatically regulated by the in-built tempera-

ture sensors and the integrated unit controls.

Condensate trap siphon
SK-HL138
Condensate trap siphon with integrated foul air infiltration prevention

system for installation recessed on wall or flush mounting.
The trap cover is transparent for easy monitoring of the water level.
Note:
Use of siphon is only recommended where gravity assisted condensate

collection is achievable.
Accessory supplied loose for fitting on site.
Pipework not included
Room CO2 sensor: CI-EE80-2CT3/T55

Room sensor for measurement of the CO2 concentration on ventilated
spaces. The 0-10V output signal can be connected to the Therm-X
unit control panel for regulation in the DCV operation. The operation is
based on the infrared principle. Auto-calibration procedure compen-
sates for the aging of the infrared source and ensures outstanding long
term stability.
Note:
Power can be provided by the unit to a single air quality sensor.

The unit only accepts input from a single air quality sensor.
Sensor supplied loose for wiring and fitting on site.

CI‑PS 1003
Room (Passive Infrared) motion sensor for occupancy detection. When
something enters into controlled space, this sensor detects heat emis-
sion from bodies and switches its contacts on or off.
The signal can be connected to the Therm-X units turning the unit on or
off accordingly.
The sensor has a detection range of 12 meters at an 90° angle and can
be mounted on walls or installed in corners. It’s possible to switch on/off
light emission diodes (LED).
Lower boundary mass sensing is 25 kilos.
