3 Technical description
3.1 Design
The EcoHeater extract air heat pump comprises two sections, a fan section and
compressor section.
Fan section Compressor section
Fan section
The fan section has a direct driven chamber fan with an EC motor and deep-
ridged filter. EcoHeater sizes 240 and 300 have double fans. The fan unit is with-
drawable. Replace the filter from the front of the unit.
Compressor section
The compressor section comprises a DX heat recovery coil, electronic expan-
sion valve, a variable speed controlled compressor, fully soldered plate heat
exchanger (between refrigerant and the liquid side), frost-protected evaporation
water outlet for outdoor operation, and integrated control equipment with electri-
cal connection.
The cooling circuit is integrated in the compressor section. The compressor and
control components are shielded from the extract air stream. The cooling circuit
is factory tested and built in accordance with PED 2014/68/EU, Module A2.
Designed in accordance with EN378.
The cooling circuit is supplied with a high-pressure switch, as well as protection
and alarm functions for high/low pressure. The cooling circuit is controlled so
freezing does not occur in the extract air coil. Refrigerant is R410a.
All piping and electrical connections are made via the front. Frost protection
(heating wire) for the condensation outlet is a maximum of 1 metre from the Eco-
Heater’s casing for outdoor operation.

Control
The EcoHeater has a factory-set time programme for continuous operation at
one speed. The time programme can be changed on the Climatix display for
control at up to three fan speeds.
• In case of malfunction of FF (extract air fan), an alarm sounds and the unit
stops.
• The EcoHeater must be interlocked via circulation pump CP1.
• If GT6 (temperature sensor water in) registers a temperature that is too high,
the compressor stops. It restarts automatically when the temperature falls to
the permitted value.
• If EP1 (pressure sensor cooling circuit) and/or GT4 (temperature sensor
exhaust air) register a temperature that is too low, the compressor’s speed is
reduced until the temperature reaches the permitted value.
• If OP1 (high-pressure sensor cooling circuit) registers a condensation tem-
perature that is too high, the speed of the compressor is reduced.
• If GT4 (temperature sensor exhaust air) is lower than 12 °C, the compressor
cannot be started.
• If GT4 (temperature sensor exhaust air) is more than 3 °C lower than GT2
(temperature sensor extract air), the compressor cannot be started.
• If GF1 (water flow sensor) registers too low flow, the compressor cannot be
started. Restart occurs automatically when the permitted flow is reached.
Compressor protection
In case of an alarm from FI (frequency inverter) or HP1 (high-pressure switch),
the compressor stops. The high-pressure switch is reset manually.
Temperature control
Temperature control to EcoHeater can be controlled via external control signal
(0-10 VDC from sub-central unit, for example, district heating central), internal
radiator curve or based on accumulation tank temperature, so that full capac-
ity from the unit is utilised before the property’s alternative energy sources are
used.
Pressure control
Pressure control can be used by GP4 maintaining a constant pressure in the
extract air duct. The current air flow can be read on the Climatix display.
If the duct pressure deviates from the setpoint after a set time, an alarm sounds.

5 Operation
5.1 Commissioning
Commissioning of the unit must be carried out by competent personnel in ac-
cordance with the separate checklist:
THE NEW EcoHeater, Start-up checklist
and according to the separate commissioning protocol:
EcoHeater, Commissioning report
The documents can be downloaded from ivprodukt.docfactory.com.
The validity of the product warranty is conditional on the system having been
commissioned correctly. Working on the unit during the warranty period without
the approval of IV Produkt shall render the warranty void.
The unit was designed and manufactured based on given operation cases
that must comply with the unit’s use for optimal function and a good operating
economy.
External circumstances should not be changed without checking that such
changes are within the unit’s intended area of operation.
When commissioning EcoHeater for an occupied property, the fan section must
be started immediately after installation to avoid disruption to the property’s
ventilation. The compressor section is then commissioned separately.
NB!
It is important that the oil inside the speed-controlled compressor
crankcase is warm before starting the heat pump. The crankcase heat-
ing must be switched on long enough before the unit begins operat-
ing so that the oil maintains a temperature of at least 30 ºC. The maxi-
mum warm-up time is approximately 2–3 hours. The temperature can be
measured externally at the bottom of the compressor.
Prior to commissioning, the contractor must:
NB:
Wiring of connections and other electrical work may only be carried out
by a qualified electrician or by service personnel recommended by IV
Produkt.

The fan transports air through the system. The fan shall overcome the flow re-
sistance found in air diffusers, ducts and units.
The fan speed is regulated to provide correct air flow. If the fan generates a low-
er air flow, this will impair the function of the ventilation system.
•If the extract air flow is too low, the ventilation capacity will be unsatisfactory.
•If a centrifugal fan is rotating in the wrong direction, the air flow will still go
the right way, but with a considerable reduction in capacity. Therefore check
the direction of rotation.
