OPERATION
TP970A,B and TP9600A,B
When using a TP970A or TP9600A (Fig. 1) in heating
applications with a normally open valve, a fall in temperature
lowers Branchline Pressure (BLP) to the valve. THis lower
BLP provides proportional valve action matching the existing
load requirements. When a TP970B or TP9600B is used in a
cooling application, a rise in temperature causes the TP970B
or TP9600B to lower BLP. The energy conservation models
limit control temperature to a maximum (heating) or minimum
(cooling) of 72F (24C).

TP970C and D
The TP970C and D with wide throttling range (Fig. 2 and 3)
allow use of heating and cooling valve assemblies with either
selected spring ranges (Fig. 4) or ratio relays (Fig. 5) to
achieve a ZEB range.
Various ZEB ranges, heating control points, and cooling
control points are obtained by selecting the appropriate
thermostat setpoint, throttling range, and spring range or ratio
relays.
