9) Technical Data

Supply : 230VAC (between 208V and 240V) - Frequency : 50/60Hz
Grounding : ! COMPULSORY !
Electrical protection :
The motor is self-protected against overloading. It is thus NOT necessary to install an electrical overload
protection device. We advise using a short circuit protection device with the following specifications :
- Starting peak of 150 A for 2 to 4 milliseconds. The "softstop" function has to be used to avoid this peak.
- We recommend a class AM or a
Recommended protection calibre/motor type

TAC 1/2
TAC 3/4
TAC 1/1
Insulation class
Thermal : B
Mechanical: IP44 - the connectors must be oriented downwards AND mount pass cables (PG) M16 or M20 on
the plastic box where you have previously punched out the holes to allow cable passage. Be cautious to punch
holes properly to keep tightness.
Ambient temperatures: -10°C / +55°C
Conformities : – UL approved

10) Other functionalities

The controller TAC5 SC provides additional functionalities. These are detailed in the complete documentation
on www.lemmens.com
- MODBUS RTU communication (with SAT MODBUS)
- MODBUS TCP/IP communication (with SAT
WIFI/Ethernet)
- KNX communication (with SAT KNX)

Only with post cooling option: this alarm indicates that the supply T° set point
cannot be reached (actual T° higher than set point during 15 minutes, or 30
minutes if comfort on T2 rather than on T5, while post cooling is at
maximum). Comfort temperature is by default the supply air temperature
measured on T5 but can also be configured via the advanced setup as that
measured on T2, that is to say the room temperature (optional sensor).
Only with post heating or cooling option: this alarm indicates that the supply
temperature (T5) is lower than 5°C. The fans are stopped during 1 minute.
The alarm is configurable through the advanced setup and is disabled by
default.
After fixing the failure, press RESET on the TAC5 SC.
Only with hydraulic post heating BA: this alarm indicates that the anti-frost
protection temperature of the hydraulic coil is lower than 4°C. The 3 ways
valve is automatically commanded to be opened at 100% during 15 minutes
and the pump contact is commanded closed (WP-WP contact on SAT
BA/KW). If the fans turn, the alarm is sent immediately; if the fans are
stopped, the alarm is sent after 5 minutes.
After fixing the failure, press RESET on the TAC5 SC circuit.
