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.
