Getting the most out of your Herpstat
(Troubleshooting)
The Herpstat has a user replaceable fuse. If the Herpstat appears to not operate while being plugged in the
fuse may have been damaged by a voltage spike or overload. Disconnect all cables to the unit including the
power. Flip the device upside down and remove the four screws. Flip the unit back over and gently lift the top
part of the enclosure off the unit. Inside you will see the fuse. Replace with a 6.3x32mm fuse with a 15 amp
rating.
NOTE: For units marked as Rev1.2 on the bottom it is important that the fuse is centered between the front fuse
holder clip and the rear fuse holder clip. There will be a gap at both ends of the fuse clips which should be
equal.
Replacements are available through the spyderrobotics.com webstore or often from local home improvement
stores. We recommend keeping spares on hand to avoid potential downtime should this scenario occur. Keep
in mind a popped fuse means you have overloaded the thermostat. The fuse popped to protect the circuit
board. Inspect your equipment. Reassemble the unit in the reverse order. Use caution to make sure the clear
ribbon cable does not get pinched between the top and bottom half of the enclosure.
Should the device not work as expected it's possible one of the menu settings was set incorrectly. It may be
easier to reset the device to its factory default settings than to figure out which setting is causing the issue. To
do this enter the menu and perform the Master Reset option under the System Settings menu.
Do not cover the probe tip with aluminum tape. This will cause false readings and poor regulation.
If possible route the probe wire so that it is not in direct contact with the 120vac cables going to the heating
devices. Preferably leave at least a few inches between the probe wires and the AC lines to avoid cross
talk/electrical interference issues.
