TS8205B Q8205A
APPLICATION
T8205B,C and TS8205B,C Electronic Pool and Spa Control
Systems are used in pool, spa, and hot tub applications to
control water temperature. T8205B,C and TS8205B,C Control
System components include a T8205A,H or TS8205A Control
Module and Q8205A-C Setpoint Panel. Sensor Assembly is
purchased separately. The T8205A and TS8205A Control
Modules and Q8205A-C Setpoint Panels can be purchased
separately. The T8205H Control Module is for use with heat
pump systems only. Q8205A-C Setpoint Panels can be used
for remote applications.
• T8205A and TS8205A Control Modules are used with a
sensor and Q8205A-C Setpoint Panel.
• T8205H Control Module is for use with heat pump
systems only and has 1/4 in. quick connect terminals.
• Module controls within 1.5°F (0.8°C) at setpoint of
106°F (41°C).
• Models available for single control or dual control of
combination pool and spa.
• Isolated relay contacts in electronic control modules
operate gas control or ignition module.
• Male quick-connect wiring terminals provided on
electronic control modules.
• Sensor with 3/16 in. female quick connects on 42 in.,
48 in., 50 in., or 96 in. leadwires can be directly
immersed or mounted in well.
• Setpoint panel can be remotely mounted.
• Plastic potentiometers and selector switches provide
increased protection from humidity and chlorine.
• Combination of 1/4 in. and 3/16 in. quick connect
terminals provide ANSI miswiring compliance, except
T8205H Control Module.
