Description
The Tjernlund Products MAC-1E Accessory Control for Adding 1 Additional 24V/115V Appliance W/UC1 is an auxiliary control module designed to expand load management capability in burner and venting control systems. In HVAC systems used in gas-fired heating and venting applications, it is paired with the main control unit to coordinate interlocked parts within a shared safety circuit. The module is mounted inside an electrical enclosure and connected through low-voltage and line-voltage terminals for controlled switching. It improves system integration flexibility, enhances operational coordination, reduces wiring complexity, and ensures stable performance of connected heating equipment under continuous demand.
