Thermistor Probe, shown above, not included. Order separately.

Features:

• Thermistor Range Adjust
• 10 AMP Load Control Relay (or higher with optional Load Power Center I)
• Deadband Control Adjust
• On/Off Control Mode
• Sensor Input (order separately): Thermistor or Platinum RTD-100ohm probe
• Ranges:
  0°F to +500°F (Thermistor input)
  -302°F to +1000°F (Platinum RTD input)
• Sensitivity ±0.05°F

• Exclusive Range Selector Design: Optimizes amplifier performance and allows universal usage of many standard type thermistors or resistance/temperature detectors (RTDs) while providing full range temperature coverage in overlapping bands.
• Coarse/Fine Setpoint Controls: Provide the highest resolution temperature adjustment and setability when used with our exclusive temperature setting charts.
• Solid State Circuitry and Transformer Design: Provides electrically safe isolation of probe input circuit for dependable operation.
• Heat/Cool Power Indicators: Continuously monitor 120VAC Load power at the Heat and Cool AC plug-in power output receptacles.
• Deadband Control: Allows precise adjustment of on/off hysteresis--0.02°F to 20°F when using thermistor probe and 0.5°F to 40°F when using Platinum RTD probe.
• Rugged Power Output Control Relay: Has 10 Amp Load rating (resistive loads on each pole). Panel replaceable 10 Amp fuse protects load relay contacts.

The VersaLab 2200 On/Off Solid State Temperature controller allows instant plug-in system setup and uses a wide range of standard thermistor or platinum RTDs. In operation, the resistance versus temperature change of the thermistor temperature sensing RTD is amplified by a solid state assembly that controls a rugged electromechanical two position relay in direct relation to the system demand and deviation from temperature setpoint. The output relay/contactor has rugged 10AMP single pole double throw contacts. These contacts are wired to alternately control the flow of 120VAC power to the heat or cool control receptacles.
