Watlow Series 146 Retrofit - Manual (Page 5)

These notes are used to signify areas of concern in changing to a retrofit choice. These notes are also printed at the end
of the retrofit listing.
Note 1: Retrofit controller requires a substitution of a 100 Ohm RTD sensor for the thermistor.
Note 2: Mounting and dimensions of retrofit controller are different. Verify that sufficient panel space and depth is
available.
Note 3: Retrofit controller outputs are different. Add external interposing mechanical or solid state relay if applicable.
Note 4: Retrofit controller has a programmable, not fixed set point. Lock set point using controller's lockout parameter.
Note 5: For DIN rail mounting or sub-panel mounting, purchase DIN rail adapter p/n 0822-0586-P001 for 1/32 DIN or
p/n 0822-0586-P002 for 1/16 DIN.
Note 6: Add a suppressor, Watlow p/n 0804-0147-0000, for inductive loads.

wires are on these pins, select a different retrofit.
Note 12: Retrofit controller does not have user selectable control action.
Note 13: Solid state sensor required for humidity. See
