Quest Controls Model 200 and 201 lead-lag controller

Quest Controls Model 200 and 201 Lead/Lag Controller is the company’s latest line of intelligent lead/lag controllers. The Model 200 features factory configured setpoints based on customer requirements, while the Model 201 allows for configuration and setpoint changes through password protected menus.

Both models provide precise control over two HVAC systems and offer a wide temperature control window to further optimize for energy savings. The Model 200 and 201 support HVAC units with built-in economizers along with units that have two stages of mechanical cooling. The controller is compact and easy to install as a replacement for a standard thermostat. Power to the controller is redundantly derived from both HVAC units so the system continues to operate if one of the HVAC units loses power. The 2×16 LCD display shows the current control mode along with reporting the shelter temperature from its built-in temperature sensor. In addition, the Model 200/201 has separate normally closed contacts for high temperature and low temperature alarming.

Key features:

• Low cost and easy replacement for ineffective lead/lag controllers.
• Enables lead/lag HVAC control at sites that currently have separate thermostats.
• Reduces energy consumption through advanced control sequences.
• Prevents short cycling of HVAC equipment.
• Provides site visibility by alarm notification.
• Prevents deviation from corporate setpoint standards.
