 Mixing Valve Reset Control Stk# 31360 uses a Liquid Crystal Display (LCD) as the method of supplying information. You use 

the LCD in order to set up and monitor the operation of your system. The Stk# 31360 has three push buttons (Item, “Up”, “Down”) for selecting, 
viewing, and adjusting settings. As you program your control, record your settings in the ADJUST menu table which is found in the second half 
of this brochure.
