MANIKSTAT

Dual temperature controller

MANIKSTAT prevents thermodynamic overpressure in heating mode and indoor coil freeze-up in cooling mode. Two probes monitor the discharge line and the suction line; the controller acts on the heat pump's Y and B circuits to protect the equipment and hold performance through shoulder seasons.

Key points

• Thermodynamic protection in heating mode (red display)
• Indoor coil freeze protection in cooling mode (blue display)
• Protects against high pressure, high current draw and overloads
• Two probes: 3/8 in. discharge line and 3/4 in. suction line
• Outputs on the heat pump's Y and B circuits
