New Features of 3rd Generation PWM
**WHY THIS MAY BE IMPORTANT FOR YOU**
• Ability to reset to any one of 3 preset temperature ranges when using FAN-PWM-TS sensor
Smart fan diagnostics detects stalled or over current fans to prevent module damage
New 16 bit MCU for increased resolution on temperature sensor input
Primary fan low power starts to reduce the current spike on electrical system
Onboard status LED and status output for vehicle interior status light
Quality Deutsch IPD connectors on the premium harness made in USA
Silicone rubber button membrane and case seals for improved durability
Improved AC input timing to minimize fan operation during defrost cycles
Single unit capable of use with both 12VDC and 24VDC systems
In an effort to add features and improve quality of the FAN-PWM the functionality of the
unit may impede previous ‘creative’ installations of FAN-PWM’s.
A brushed DC motor MUST be connected to the fan output or the unit will report an
error code. Possible use with very low power (<4A) fans and non SPAL products may
also cause fan not found error code. SPAL USA will not guaranty this products function-
ality with NON SPAL fans as too often specications are unknown.
Over current protection means that the output will SHUT DOWN if the measured fan
continuous run current increases above 30A for extended periods. If running a fan ap-
proaching this amount of current draw (>25A), SPAL USA recommends that the installa-
tion also include a status light so the operator will be aware of fan status. See page 8 for
status light wiring.
Because of timing sequences on the AC input wire when using a manual override
switch there will be a delay before the fan turns on/off with the switch.
