INTRODUCTION
The Temp-Tracker 2-stage and 4-stage temperature
controllers (Controller) are designed to be mounted on
heaters with two or four stages of operation in order to
provide accurate water temperature control in a variety
of applications. They can also provide sequencing with
lead/lag on two boilers. The Controllers may be used
to provide a setpoint temperature, outdoor reset with
reset override, or dedicated domestic hot water (DHW)
generation and several options for external heater
control. An additional relay contact is included with the
“shipped loose” version to provide an alarm signal in
case of a sensor failure.
When shipped loose, this package includes:
(1) Controller in enclosure
(3) Water sensors
(1) Outdoor air sensor (optional)
(1) Well Assembly
USER INTERFACE
The Controller uses a Liquid Crystal Display (LCD) as
a method of supplying information. Use the LCD to
setup and monitor the operation of your system. The
Controller uses three push buttons (

selecting and adjusting the settings (see Fig. 3). As
you program your Controller, record your settings in
the actual settings columns of the Adjust menu in
tables G & H, found on pages 20 & 21.
Menu
All of the items displayed by the Controller are organ-
ized into two menus. These menus are listed on the
upper right-hand side of the display (Menu Field). The
default menu for Controller is the View menu. While in

NOTE:
Minimum 18 AWG, 105°C, stranded wire
must be used for all low voltage (less than 30 volts)
external connections to the unit. Solid conductors
should not be used because they can cause
excessive tension on contact points. Install conduit
as appropriate. All high voltage wires must be the
same size (105°C, stranded wire) as the ones on the
unit or larger.
