control is safely installed according to all applicable codes 
and standards. This electronic control is not intended for 
uses as a primary limit control. Other controls that are 

Choose the placement of the Timer early in the construction 
process to enable proper wiring during rough-in.
Consider the following:

Interior Wall.
Keep dry. Avoid potential leakage onto the control.
92% RH up to 104°F (40°C), down to 50% from 104 
to 122°F (40 to 50°C). Non-condensing environment.
No exposure to extreme temperatures below 32°F (0°C) 
or above 122°F (50°C).
Away from equipment, appliances, or other sources of 
electrical interference.


Rough-In Wiring

Easy access for wiring, viewing, and adjusting the 
display screen.
Approximately 5 ft. (1.5m) off the finished floor.

Use standard 18 AWG wire for the timer power, tN4, and 
relay contact connections.

Refer to the diagram below to determine the number of 
conductors to run from each piece of equipment to the 
timer location.

intended and certified as safety limits must be placed into
