the locknut to hold the conduit and enclosure base together
Install and screw the cover to the base
• If screws are used to afx the enclosure to the wall, make sure to
seal around the sensor and wall except from the bottom
Class 1 voltage wiring (low voltage)
must use a different knockout and
conduit from any Class 2 voltage

• The Multi-MOD Platinum is designed to connect to a Heat-Timer
temperature sensor (HT# 904250-00) The sensor must be
inserted into a 3/8ID well (HT# 904011-00)
• Locate the sensor in the common header where it will register the
output before any takeoffs If the sensor cannot read the output
of all the stages, it will not be able to control the system properly
