Tjernlund Products MAC1E Control
The Tjernlund MAC1E Multiple Appliance Control is an essential interface for sequencing draft inducers or power venters with multiple heating appliances. Specifically designed for 24 VAC control circuits, this interlock control allows a single exhaust fan to serve up to two separate gas-fired burners or water heaters. When any appliance calls for heat, the MAC1E energizes the fan and verifies the pressure switch circuit before allowing the burner to fire. This prevents flue gas spillage and ensures consistent combustion air flow across all connected equipment. The solid-state design provides reliable switching without the mechanical failure points common in generic relays, making it a standard for complex venting systems in commercial and residential mechanical rooms.
Key Benefits- System Integration: Simplifies the simultaneous control of two appliances using a single Tjernlund power venter or draft inducer.
- Enhanced Safety: Integrated interlock logic ensures the venter is at full speed before the gas valve opens.
- Contractor Grade: Features a 4" x 4" J-box mounting configuration for rapid installation and wiring within existing electrical enclosures.
- Universal Compatibility: Works seamlessly with 24V thermostat circuits and millivolt systems using supplementary transformers.
Can I connect more than two appliances to a single MAC1E?
A single MAC1E is rated for two appliances. For systems with three or more appliances, additional MAC1E units must be daisy-chained to maintain proper sequencing and safety signal verification.
Does the MAC1E provide its own power to the gas valve?
No, the MAC1E operates as a dry-contact or switching interface. It utilizes the 24V signal from the appliance's own control transformer to trigger the venting sequence.
Is this control compatible with all Tjernlund venter models?
Yes, the MAC1E is designed to interface with the standard 24V trigger leads found on Tjernlund series fans, including the GPAK, VP, and HS models.
