•
Do not open control.
•
Do not attempt to replace any
components.
Mounting
The control should be mounted
in accordance with the burner
manufacturer’s or appliance
manufacturer’s instructions. If this is
a replacement application, mount the
control in the same location as the existing
control. The 7590 control is designed to
mount on a 4” x 4” junction box on the
burner. Avoid mounting locations where
water could drip on the control. Mounting
location must remain within the -40°F
(-40°C) to +175°F (79.4°C) operating
temperature range.
Mounting location should protect against
moisture, corrosive chemicals, excessive
dust or water. If any of the above
elements are present, control should be
mounted in a NEMA 4 rated enclosure.
Transformer Sizing
A transformer with a 24 volt secondary
is required to power the control and gas
valve. To calculate the minimum VA
transformer needed:
Voltage X Amperage = VA rating needed
Voltage = 24 Vac
Amps (0.2 amps + gas valve current draw)
Example:
0.2A (7590) + 0.5A (gas valve) = 0.7 A
0.7A X 24V = 16.8 VA or 20 VA transformer
Spark Gap
Follow appliance manufacturer’s or burner
manufacturer’s instructions for setting the
proper ignition electrode spark gap.
Electrical Shock
Hazard
Electrical shock can cause
severe personal injury or
death.
Make sure all wiring is securely installed
on the control. Failure to secure the wiring
properly can lead to electrical shock.
Incorrect Wiring
Will Result in
Improper Control Operation
•
Label all wires prior to
disconnection when servicing
controls
•
GeniSys wiring order and colors
may not match the wire order and
colors of the appliance or other
manufacturers’ controls.
•
The GeniSys Control should be
wired according to the appliance
manufacturer’s instructions.
DO NOT connect
any cell phone,
tablet or computer to the
communications port. Any device
connected to the port will be
damaged.

To Prevent
Shock or
Damage to the Appliance or the
Control, Remove Power Before
Making Any Wiring Connections.
Do not short out gas valve or control
terminals during testing. Shorting could
cause damage to the thermostat or
control and could cause personal injury or
property damage.
