UC1 Universal Control 
The UC1 is the new standard interlock control for Tjernlund's full line of Fixed Speed Power Venters, Draft Inducers and Combustion Air In-Forcers. It can be interlocked with virtually any burner control circuit.  Features include: adjustable pre & post purge, LED status / diagnostic indicators, 10 second prover switch delay to avoid burner start up and wind induced short cycling.  Interlocks with any 24-120 VAC burner control circuit and also includes “dry” contact actuation option. Selectable voltage eliminates false activation by burner control circuits.  After each burner cycle the UC1 will continue to operate in post-purge mode to allow the venter to purge the heater and vent of residual flue gases.  A factory post-purge time is set at 2 minutes and is adjustable up to 16 minutes.

MAC1E & MAC4E Multiple Appliance Controls
(Compatible with UC1 Universal Control only)
 
MAC1E MULTIPLE APPLIANCE CONTROL
Used in conjunction with the UC1 Universal Control to easily interlock up to one additional 24 VAC , 115 VAC or millivolt controlled appliance with
Fixed Speed Auto-Draft Inducer , Power Venters (Gas, Oil), Draft Inducers, or In-forcers.  It activates the Venter through its connections to the UC1 and in turn relies on the UC1 Fan Prover safety circuit (P1 & P2) to allow its interlocked appliances to operate.  Any pre/post-purge settings on the UC1 will be defaulted to the MAC1E. The MAC1E puts an end to difficult and costly job site wiring nightmares.   Circuit board housed in oversized 18 gauge electrical box with multiple knock-outs for easy wiring connections.

MAC4E MULTIPLE APPLIANCE CONTROL  
Used in conjunction with the UC1 Universal Control to easily interlock up to 4 additional 24 VAC, 115 VAC or millivolt controlled appliances with
Fixed Speed Auto-Draft Inducers,
Power Venters (Gas, Oil), Draft Inducers, or In-forcers.  It activates the Venter through its connections to the UC1 and in turn relies on the UC1 Fan Prover safety circuit (P1 & P2) to allow its interlocked appliances to operate.  Any pre/post-purge settings on the UC1 will be defaulted to the MAC4E.  The MAC4E puts an end to difficult and costly job site wiring nightmares.   Circuit board housed in oversized 18 gauge electrical box with multiple knock-outs for easy wiring connections.

Gas Water Heater Interlock Kits

WHKE MILLIVOLT INTERLOCK KIT FOR USE WITH UC1 CONTROL
For use with the UC1 Universal  Control, MAC1E or MAC4E auxiliary controls.  The WHKE gas pressure switch actuates the Inducer /Venter through the A-B dry contacts on UC1, MAC1E or MAC4E.  The Linear Limit switch disables the heater in the event of a venting malfunction.  Includes JA1 thermocouple junction adapter.  To interlock millivolt water heater(s) only with a UC1 controlled Inducer / Venter add a WHKE for each millivolt heater.  To interlock a millivolt water heater and one 24/115 VAC furnace or boiler with a UC1 controlled Inducer / Venter, add a WHKE and a MAC1E.

Single Acting Galvanized 
Control For Oil, Solid Fuel and Fan
Assisted Gas Burners
 
Barometric Damper
DCG Series:
Double Acting Galvanized Control
For Gas Heating Appliances
 
This single acting control is made of galvanized steel for low maintenance and corrosion resistance. It has integral anchor points and self- aligning, self-centering rocker bearings for long  lasting service.  A cushioned stop minimizes rattle and noise. Adjustment is easily accomplished by moving counter weight on outside tab.  
  This quality engineered control is double acting  for installation on gas fired appliances.  It has many practical features including: self-aligning,  self-centering rocker bearings, polished chrome adjustment knob, ultra-light sensitivity and rugged, galvanized construction.
   
 

TYPICAL DRAFT CONTROL INSTALLATION

The Problem:
Heating appliances are designed to
operate with a consistent draft. Chimney
configurations, mechanical draft fans 
and weather can cause draft fluctuations.
These fluctuations result in inefficient
combustion and more frequent service
calls.
The Solution:
Draft controls regulate the airflow through 
a chimney or vent.  By diluting the
chimney/vent draft with varying amounts
of room air they maintain the draft at a
heater's flue outlet within a consistent,
safe and efficient range.
