User Interface
The Mixing Control 362 is a microprocessor base control designed to operate either a variable speed injection
pump or a floating action mixing valve in order to provide a mixed supply water temperature to a hydronic
system. The control is designed to operate in two distinct modes. Mode 1 allows for the control to provide a
reset mixed supply water temperature to maximize the comfort and efficiency of a hydronic heating system.
Multiple zone temperature control is achieved by using either thermostats or tekmar Zone Controls. Mode 2
allows for control of a snow melting slab. Standard features include boiler protection (when a boiler sensor
is installed), pump exercising, and digital temperature readouts.
Access Level(s) The tekmar Mixing Control 362 has four access levels which are LTD (limited), USER, INST (Installer), and ADV
(advanced). This brochure only covers the LTD (Limited) and USER levels. Only qualified service people should adjust the INST
(Installer) and ADV (advanced) access levels.
Additional information can be gained by observing the Status and Pointers fields of the LCD. The status field will indicate which of the
control’s outputs are currently active. Most symbols in the status field are only visible when the View Menu is selected.
