DESCRIPTION
The COP2 Constant Operating Pressure Control includes a VFD that will modulate the speed of an approved Tjernlund exhaust
fan to maintain a user adjustable negative pressure set point. The set point is adjusted through dip switches mounted on the COP2
circuit board. The operating range of the COP2 control is -0.05” W.C. to -0.53” W.C. in 0.01” W.C. increments.
Pressure is measured in a chase, duct or vent at the farthest point from the exhaust fan with the pressure transducer and sensing
tube kit. As exhaust volume increases within the duct/chase/vent the resulting reduction in measured pressure causes the COP2
control VFD to speed the fan up to handle the additional exhaust volume and slow the fan down when the exhaust volume is
reduced to maintain a constant exhaust pressure.
GENERAL INFORMATION
Each COP2 is electrically factory line tested before shipment.
After opening carton, inspect thoroughly for hidden damage. If any damage is found notify freight carrier and your distributor imme-
diately and file a concealed damage claim.
INSTALLATION RESTRICTIONS
1. Do not use the COP2 with gas or oil fired heating equipment without interlocking all burners being served with a CIC1 Interlock
Control and the required number of MAC-Series Multiple Appliance Controls. The interlock feature is not activated unless a
jumper is installed between “A” and “GND” of the COP2 operational mode terminal strip. Follow instructions and wiring dia-
grams included with the CIC1 Interlock Control and perform operation check to validate the interface with the COP2 Control.
2. The COP2 is intended for indoor installation only. Do not mount the COP2 on a heat source or in an environment that exceeds
104oF (40oC).
3. The maximum distance wire can be ran from the COP2 Control to Fan Motor is 100 feet.
The maximum distance wire can be ran from the COP2 Control to Pressure Transducer is 250 feet. Transducer wiring
should be in metal conduit or utilize shielded cable.
CAUTIONS
The COP2 must be installed by a qualified installer (an individual properly licensed and/or trained) in accordance with all local
codes or, in their absence, in accordance with the National Electrical Code. Failure to install, maintain and/or operate the COP2 in
accordance with manufacturer's instructions may result in conditions which can produce bodily injury and property damage.
1. Disconnect power supply from the COP2 when making wiring connections and servicing the COP2. Failure to do so may result
in personal injury and/or equipment damage.
2. All installation restrictions and instructions in the Tjernlund Fan installation instructions must be followed when using the COP2.
3. Make certain power source is adequate for the COP2 and Tjernlund Fan requirements. Do not add equipment to a circuit when
the total electrical load is unknown.
