How To Install a Spa Thermostat Control

Like all thermostats, a spa thermostat is intended to control the temperature by heating or cooling a system, in this case, the water inside a spa. First of all, keep in mind that the thermostat is the main component of the heater that heats up the water of the spa. There are two main types of spa heaters: the electric heater is used in spas that are situated above ground level and the gas heater is usually installed to spas at ground level.

A typical spa thermostat functions in a way similar to a domestic home thermostat. The spa thermostat needs electric power to work properly. Usually, the power required is about 110 volts. The thermostat and the water filter are the two principal components of the equipment of the spa. There are several types of thermostats and when one is going to purchase a thermostat, keep in mind that all of them do the very same job: to measure and indicate the temperature of the water of the spa.

The spa thermostat is located within the control center of the spa, and it sets the temperature desired by those who use the spa. For some reason or other, you might find the need to change or the thermostat control and install a new one.  If you are up for the job here are the important steps you should follow:

  1. First of all, turn off the electric power supply and have the following tools handy: screw drivers (small, as well as flat headed ones), long nose pliers and wire strippers.
  2. Remove the front cover as well as the thermostat base by unscrewing the mounting hardware. This holds all the wiring and connections.
  3. Usually, wires are color-coded in order to be easily recognized.  If this is not the case here, label each wire so that you will have no trouble re-assembling afterwards.
  4. Disconnect all wires from the terminal with a screwdriver.
  5. Separate the front of your new thermostat from the base, and place the base in position so that the now loose wires protrude from the center opening.
  6. Mark the screw holes with a pencil, remove the base and drill appropriate holes in the marked screw locations.
  7. Tap a plastic anchor in each of the holes and reposition the thermostat base.
  8. Feed the wires through the centre opening and secure the base with the screws provided.
  9. With a screwdriver, reattach all wires to their appropriate terminal.
  10. Press the reset button to clear the program memory and attach the control unit to the base.
  11. Turn the power back on and test your thermostat to check that it is functioning properly. 

Spas can be very relaxing but at the same time, they can be very dangerous, especially if they are the electric type. The thermostat helps regulate the temperature, so that the spa will provide a relaxing experience, but will not provide too much heat as to suffocate the user and cause serious health problems.
