Laars Heating Systems FT1868 Cascade System Sensor for Mascot FT Boilers

The Laars Heating Systems FT1868 is a critical component for multi-boiler cascade systems using Mascot FT Series condensing boilers. This cascade system sensor must be connected to the Leader boiler in order to provide feedback for the system set point reference and therefore properly control the cascaded boilers. Only one Mascot System Sensor is needed per cascade system, regardless of the number of boilers installed.

Key Features:

• Monitors system water temperature and provides feedback to the leader boiler for precise temperature control
• Essential for proper operation of Laars Mascot FT Series cascade systems with up to 20 boilers
• Connects to the dedicated cascade system sensor terminals on the leader boiler
• Cascade mode operates via system sensor with units shutting off when system sensor reaches system target
• Works in conjunction with cascade communication cables (sold separately) to coordinate multi-boiler operation

The sensor is strapped to the system piping and thoroughly insulated along with the piping. It provides critical temperature feedback that allows the cascade system to sequence multiple boilers efficiently, bringing additional boilers online as heating demand increases and shutting them down as demand is met. During normal operation boiler setpoint is defaulted to 20°F higher than the system setpoint to a maximum of 180°F setting.

Installation: The sensor leads connect to terminals marked "Cascade System Sensor" on the leader boiler's terminal strip. Proper sensor location and insulation are critical for accurate system operation.

Compatibility: Designed specifically for use with Laars Mascot FT Series wall-mounted and floor-standing condensing boilers in cascade configurations.
