ICM Controls SC5811 Thermostat

The ICM Controls SC5811 is a high-performance programmable thermostat designed for 2-stage heat/2-stage cool systems and multi-stage heat pump applications. Engineered with a hardwired 24V connection (R, C, W1/O/B, Y1, W2, Y2, G, S1, S2), this unit is a professional-grade replacement for the SC4811 and 9555 models. It features SimpleSet technical programming, allowing technicians to rapidly transfer configuration settings between units, significantly reducing time on the job site. The integrated ICM patented Thermal Intrusion Barrier prevents drafts from the wall cavity from affecting the accuracy of the temperature sensor, ensuring tight temperature differential control within ±1°F.

Built for versatile scheduling, the SC5811 supports 7-day, 5-2, or 5-1-1 programming modes with four daily periods. The interface utilizes durable soft buttons and a backlit display for clear visibility in low-light utility spaces. Advanced field settings include auto-changeover, keypad lockout for high-traffic areas, and min/max temperature limiting to prevent energy waste. For unbalanced zones or remote monitoring, the SC5811 is fully compatible with remote sensing probes via terminals S1 and S2, allowing for accurate indoor or outdoor temperature feedback.

• Direct Replacement Compatibility: Seamlessly replaces legacy SC4811 and 9555 thermostats, utilizing existing wiring footprints in most 2-stage heat/2-stage cool setups.
• Precision Control: Features adjustable temperature differential and auto-changeover to maintain tight setpoints without system short-cycling.
• Field Reliability: Hardwired 24 VAC operation with permanent memory retention ensures user settings remain intact during power interruptions.
• Security Features: Integrated keypad lockout and setpoint limiting provide control over occupant adjustments in commercial or rental applications.
• Advanced Diagnostics: Built-in status LEDs provide immediate visual feedback on system calls for heating or cooling stages.

Can the SC5811 control a 2-stage heat pump with auxiliary heat?
Yes, the SC5811 is fully configurable for 2-stage heat pump systems and accommodates auxiliary heat stages through its comprehensive terminal block.

How does SimpleSet programming work for bulk installs?
Using an ICM master thermostat, you can "push" all configuration settings directly to the SC5811, bypassing manual menu navigation for every unit on a multi-family or commercial project.

Does this unit require batteries for memory backup?
No, this is a hardwired thermostat that uses permanent memory to store all programmable schedules and installer settings without the need for periodic battery replacement.
