ENVISION POOL HEATER INSTALLATION MANUAL
To Change Between Pool and Spa Setpoints Manually:
This is the default factory setting (jumper on pins 1-2)
and allows the use to change between the pool and spa
setpoints by using the mode button located on the front
control panel. The use of an external water pressure switch
IS NOT
required for this mode of operation.
To Change Between Pool and Spa Setpoints Automatically:
This change can be done automatically as the water flow
is directed to either the pool or spa. The use of an external
water pressure switch in the spa piping
IS
necessary. A
two-wire control circuit must be connected from the water
pressure switch to the terminals 9 and 10 on the terminal
strip located in the electrical control enclosure. The mode
jumper must be on pins 2-3 for this mode of operation. See
the Terminal Strip and Mode Configuration Pins illustration
for pin settings.
Remote Thermostats and Controllers:
If a remote thermostat or another control system is to be
used to operate the heater, a normally open dry contact
can be made at terminals 11 and 12 on the terminal strip
located in the electrical control enclosure. Remove the
red jumper from terminals 11 and 12 on the terminal strip
and install the remote control system. The mode jumper
must be on pins 3-4 for this mode of operation. See the
Terminal Strip and Mode Configuration Pins illustration for
pin settings.

Temperature Setpoint
Temperature setpoint maximum for POOL mode is 95°F
•
(35°C).
Temperature setpoint maximum for SPA mode is 140°F
•
(40°C).
To change the temperature setpoint, press the POOL/
SPA/STANDBY button until you reach either POOL or SPA
mode, this will prompt the control to display the current
temperature setpoint. Hold either UP or DOWN button to
scroll to your desired temperature setpoint. Once your new
temperature setpoint has been reached, release the UP
or DOWN button. Your new setpoint will be displayed for
fifteen seconds then revert back to the actual pool or spa
water temperature.
NOTE:
When the mode jumper is in position 3-4, the
setpoint must be changed on the remote control system.
Selecting Pool or Spa Mode
Press the POOL/SPA/STANDBY button until you reach the
desired mode. The LED indicator light will verify the mode
that has been selected. NOTE: When the mode jumper is in
position 2-3 or 3-4 the mode is determined by the external
water pressure (flow) switch or remote controller.
