Part # T104P201
These heavy-duty Mechanical Time Switches are designed for commercial, industrial and residential applications and have the highest motor load ratings in the industry. They provide up to 12 ON/OFF operations each day with a minimum ON/OFF time of 1 hour.
This model is designed to turn OFF a gas fired swimming pool heater approximately 20 minutes before the filter pump shuts down. This eliminates the problem of pounding and knocking due to overheated water, reduces scale and lime deposits and extends the service life of the heater

how do you test the function of the fireman's switch? I have an intermatic T104P201 with the firemans switch connected to a Jandy JXI pro series heater. I want to confirm that it is in fact shutting down the heater 20 mins before the pool filter.
Hi, Kevin. Your heater will not operate if the switch isn't working. You can test the switch to see if it is open (good) closed (bad) while the unit suppose to be running.
I have a pool pump and booster pump, both with timers. Can I use this to ensure that the booster pump doesn't run without the main pump being on? So, basically instead of wiring it to the heater, I could send the signal to the booster pump instead?
I have an Intermatic T104P201 timer for my pool, it's 16 years old, doesn't seem to be advancing and turning pool on/off.
Is the T104M the correct replacement mechanism? The box is in good condition. I don't have a heater on the pool, so not sure why I haven this timer, but it's always worked well until now.
Many thanks, JL
The time dial keeps sticking, causing the pump not to turn on. Time for a new timer or is there a fix?
Hello Linda, depending on what model you have and hooked up for 220v please check inside unit to check model.
Is there a timer for coordinated control of a pump and an electric in-line heater?
Hi Robert, There is not a timer that can control a heater and pump. Heaters are not put on timers because they are activated by the water flow.
can I just buy a new cover for model T104P201 the part no#2T2503A
Yes you can buy just the enclosure. There is the Intermatic Plastic Time Clock Enclosure Only or the PF1000 Series Intermatic Metal Time Clock Enclosure Only.
