How to lock Hayward Heater at Rental Property

[djkoell]

Hi there. I searched the forums but couldn't come across any past answers on how to lockout a Hayward pool heater at a short term rental property. We have a 400k BTU Hayward heater. I came across the following kit on Amazon but couldn't find anything on other sites or any reviews on the effectiveness of this product.

Does anyone have experience on how to lockout a pool heater so renters don't unnecessarily heat the pool?

Thanks in advance!

TEMPERATURE LOCK-OUT:
The digital thermostat in this pool heater allows the user to lock the maximum temperature setting allowed.
This feature is useful for preventing unauthorized users from manually adjusting the temperature settings higher than desired. On a new heater, the maximum allowed temperature lock settings are initially set at the factory to 90°F for POOL mode, and 104°F for SPA mode. To adjust these settings, use the following procedure:
1. Use the MODE button to put the heater in STANDBY mode.
2. Press and hold both the UP and DOWN buttons at the same time.
3. After 3 seconds, the thermostat enters maximum temperature lock adjustment mode.
4. The SPA indicator light illuminates and the numeric display shows the current SPA mode maximum temperature lock setting. Both the SPA indicator light and the numeric display flashes rapidly when in adjustment mode.
5. Use the UP and DOWN buttons to set the desired maximum temperature lock setting. When finished, press the MODE button.
6. The POOL indicator light illuminates and the numeric display shows the current POOL mode maximum temperature lock setting. Both the POOL indicator light and the numeric display flashes rapidly when in adjustment mode.
7. Use the UP and DOWN buttons to set the desired maximum temperature lock. When finished, press the MODE button.
8. The heater will return to STANDBY mode.

What model is the heater?

If you don't want the heater to be used at all, you could disconnect the power.

It's an H400FD. Has a simple soft panel with a couple buttons located under the dark cover on the top right corner of the heater.



We thought about putting a lock on the circuit panel nearby, but thought we couldn't since there are multiple circuits in the panel and others may need to get in to turn other breakers off if something happened. The gas shut off (see yellow valve in photo above) could also be an option...

If you are comfortable going into the panel, you could disconnect the power from the breaker and cap the wires.

The fence seems to be too close to the heater. Is there at least 6" of clearance?

They sell gas shutoff valves that have a spot for a padlock on them. You could probably switch out the shutoff valve you have on there with one of those.
