IP55 terminal box located on
the outside of the heat reco-
very casing for easy wiring
access.

Condensationdrain
Drain pipe to evacuate water
from condensation.
Robust construction
High quality finishing with
aluminium profile structure,
providing a robust assembly.
2 high-efficiency filters
2 filters:
F7 filter for inlet air (filtration
efficiency: >80%).
G4 filter for extracted air (effi-
ciency: >90%).
Airtight connectors
Inlet and discharge circular
duct connection flanges with
integrated rubber air seal.
Vertical construction
Specific models for vertical
installation.
Low noise level
Internally lined with 25 mm M0
fire resistant acoustic
insulation.
Easy to mount
Single phase models integrated
hanging supports to install the
heat recovery unit.
Version with by pass
Versions with by pass enabling
100% of the air to by pass the
heat recovery (65% in single-
phase versions).
The by-pass works with a remo-
tely activated servomotor with a
manual switch (not included).

Versions CADB-D/DC/DI Regulation with an electronic microprocessor
Versions that incorporate an electronic microprocessor (BASIC,
PROGRAM, ADVANZ or DOMO) that enables fan speed control.

Versions with an electronic microprocesor: Models and functions
BASIC PROGRAM ADVANZ DOMO
Manual fan speed selection: OFF + 3 speed
Manual fan speed selection: OFF + control of speed range [MIN-MAX] (alternative to 1 )
Imbalance between impulsion and extraction flow only for VAV versions with double inverter (does not apply to 3 speed versions)
Automatic control of fan speed: CO2, CO2/VOC and HR sensors with programmable PPM or HR range (by the installer); available for 3 speed versions and variable speed versions
Remote function of the fan speed signal is 0-10V (alternative to 4 )
Booster via remote NC contact at a pre-set time. Time can be altered by software
Remote "Boost" management by NC contact or proximity sensor (alternative to 6 and 8 )
Unit can be switched ON/OFF via remote switch (alternative to 6 or 7 )
Weekly programs
Prevention of icing of the heat exchanger (simple strategy): blower fan moves to low/off; Setting the extractor fan to maximum speed.
Prevention of build-up of frost in the heat exchanger: proportional mode management with pre-heating coils (alternative to 10 or 12 )
Exchanger frost prevention: Personalized funcions (through a switch NO-NC (alternative to 10 and 11 )
Management of electric post-heating (simple or double stage) in ON/OFF mode. The objec-tive is to attain the average internal temperature value (Tr)
Management of electric post-heating in proportional mode. The objective is to attain the average internal temperature value (Tr) and to keep the impelled air within a set range (Ti)

PULSER Electronic controller to regulate the heat output for single phase electric heater battery up to 16A, in order to maintain a constant pre-select-ed temperature.Depending on the selected temperature, the controller pulses the entire power output anduses a time-proportional control to main-tain that temperature. The PULSER incorpo-rates a built-in room temperature sensor with an input for external sensor. IP-30. Maximum heaterpower 3,6kW.
PULSER-ADDSupplementary unit for slave control fromanother PULSER to control batteries withpower ratings superior to the PULSERcapacity (3600W -16A- 230V).
TTC-25Electronic controller to regulate the heat output for three phase electric heater battery up to 25A, in order to maintain a constant pre-selected temperature.Depending on the selected temperature, thecontroller pulses the entire power output and uses a time-proportional control to maintain that temperature. The TTC-25 is designed to be fitted in a cabinet on DIN-rail. IP-20.
TG-R430Room sensor with set point adjustmentbetween 0 and +30ºC.
PULSER MElectronic controller similar to the PULSER, incorporating in addition, input for an external duct sensor to control minimum or maximum temperature limitations. IP-30. Maximum hea-terpower 3,6kW.
PULSER DElectronic controller to regulate the heat out-put for single phase electric heater battery up to 16A, in order to maintain a constant pre-selected temperature.Depending on the selected temperature, the controller pulses the entire power output and uses a time-proportional control to maintain that temperature. The PULSER D is designed to be fitted in a cabinet on DIN-rail. IP-20. Maximum heater power 3,6kW.).
TBI-10Potentiometer mounted on the main board panel for setting temperature between -20 and +10ºC. Used with the PULSER-D or TTC-25 mounted within cabinet, to set the minimum air temperature before entering in the heat exchanger.
