Air Grille Distribution - all units are equipped with both deflector blades and independent directional vanes, enabling supply air to be
automatically distributed, and air flow and direction to be customized.
Microprocessor controls (S3 type)
The PCB (printed circuit board) Modbus microprocessor controls functionality of the indoor-fan motor, water valves (ON/OFF or
modulating) and electric heater (optional), to maintain room conditions at a user-defined set point. Temperature settings, fan speeds
and other control functions can be changed by either infrared handset or wired wall pad.
Electro-mechanical controls (W3 type)
A 24VAC power strip is provided. Louver stepping motor controlled from PCB. Normally open or normally closed contacts are
standard, allowing connection and control of field devices.
• High efficiency EC motor.
• Cool, Heat, Auto, Dehumidifier and Fan modes.
• Sleep, Auto-Fan, Daily Timer, Auto-Restart with memory functions.
• User friendly remote control.
• Heat and cool temperature protections and safety cut out.
• Manual control panel in cabinet.
• Auxiliary switch for cooling and heating signal.
