Description
n
The VisuGuard LCD T/P series automatically mixes hot and cold water to deliver blended
water within a specified range. Powerful advanced thermal actuator quickly compensates
for both temperature and pressure fluctuation. In the event of cold water failure, the ther-
mostatic actuator virtually shuts off the flow of hot water. The VisuGuard LCD T/P meets the
most stringent performance defined in ASSE 1016 Type T/P standard. The VisuGuard LCD
T/P comes complete with battery operated LCD temperature display in Farenheit or Celsius
for use in bath & shower applications.
Battery and temperature display are housed in an easy-access, watertight enclosure. The
accuracy and reliability of the F727 & C727 VisuGuard LCD T/P make it preferable for appli-
cations that require precise, consistent water control for showers, baths, hospital hydro-
therapy and residential areas. Both the F727 & C727 VisuGuard LCD T/P meet the American
with Disabilities Act (ADA).

NOTICE
1) Set point cannot be less than the cold water temperature. For best operation, hot and cold water should be at least 10°F (5.5°C) from
desired set point.
2) All F727 and C727 VisuGuard LCD T/P combination mixing valves meet above performance specifications based on typical operating
conditions as stated in ASSE 1016 standard.
3) If your operating conditions vary from the standard, performance may vary as well. Consult your sales representative or Powers'
Technical Support @ 800.669.5430 to discuss your specific application.
Operation
n
Hot and cold water enter respective ports in the valve and mix in a chamber containing
an advanced thermal actuator (see Figure 1). This actuator controls the position of the
plunger and temperature. Rotating the handle repositions the plunger in the cartridge
assembly to produce the desired temperature. The mixed water passes over the shutoff
disc to the outlet. If the hot or cold supply water pressure or temperature changes,
the thermal actuator will contract or expand. The movement repositions the plunger to
maintain the desired temperature.
A high temperature limit stop restricts the movement of the handle. All F727 & C727
VisuGuard LCD T/P valves are factory set to deliver tempered water up to 110°F (43°C)
with equal pressure, with hot water temperature 140°F (60°C) and cold water tempera-
ture 60°F (16°C).
