Question about Intermatic 24 Hour Electronic Timer

1 Answer

Intermatic PF 1102 digital timer with freeze control; Timer will switch from off to on to auto, but when switching to "on' the pump will not turn on. There is a "click" that indicates to me that something tried to take place. The temp switch is set that the pump should turn on at a temp of about 40 degrees or lower and the outside temp was below 32 degrees. Is this a timer problem or a thermostat problem?

The freeze control is wired parallel with timer, so both controls can turn Load ON-OFF.
So Load turns ON when either the freeze-control or the timer turns ON.
When both are ON, then Load will be ON.
Freeze control can be ON and timer OFF and Load is ON
Freeze control can be OFF and timer ON and Load is ON.
Only when both Freeze control and timer are OFF, will Load be OFF.

If pump is not turning ON below 32 (or the protection set point), then freeze control thermostat is suspect.
But you need to check if pump turns ON when timer turns ON.
If pump operates with timer, then freeze control is main suspect, unless there is a loose wire.
Open box and check for loose and burned connections.
If pump does not operate with either timer or freeze control, then check for loose wires and also check your circuit breaker and check that pump is operable.

To find replacement freeze control, Google search: Intermatic freeze protection thermostat

http://waterheatertimer.org/How-to-wire-Intermatic-control-centers.html

Which control center do you have?
Does control center have two mechanical T104 timers?
Or does control center have digital 3-channel P1353?
How many circuit breakers are located in the panel?

Your heater can be controlled with thermostat, and with automatic cut-off using fireman switch connection.
Your cleaner can be controlled by one timer, and pump controlled by second timer. Or with digital timer, the cleaner controlled by one channel, and pump controlled by another channel.

Intermatic t1202T 240v dual pool timer. Main pump continues to run and manual overide will not shut it off. Changed the timer mechanisim and same thing. Disconnected the Freeze control and it wil


Maybe the PF1202?
Probably just the freeze thermostat and not the relay.
Disconnect freeze thermostat wires from relay... and substitute a single-pole switch.
Be careful... power is ON

Do not leave the single-pole switch connected since 15 amp rating of typical switch is less than amp rating for 40 amp pool centers

I want to know how to set the time on my swimmimg pool timers


Hello Gerhard
1) Unknown brand name pool timer, probably Intermatic:
Unknown if this is mechanical timer, or digital, or remote control, or air activated. Or if this is control center with circuit breakers and multiple timers to control heater, and pool pump, or if unit has firemans switch to turn pool heater off 20 minutes before pool pump, or if unit has freeze protection thermostat, etc

Just intstalled a T104M according to the diagram and all the diagrams found on the web. The clock timer doesn't work. I can manually shut off the pump from the timer. I thought it was a bad tim


T104M is 208-277 timer mechanism that fits inside any Intermatic enclosure.
If voltage is not correct, then clock motor will not operate.
Since you did not say what voltage, I assume you have 240Volt pool pump.
Open following link to see the many ways to wire this timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
It is possible that you have the Load and Line wires reversed.
Line wire come from circuit breaker, and Load wires go to pump.

If the T104M mechanism is part of a control panel with more than one timer, and/or a freeze control, then re-post question with more specific information.

I need help to install pool pump to mechanical intermatic timer switch GE to replace the digital control.


Question is not clear.
Add a comment with missing information for exact wiring diagrams.
Voltage is not known.
Timer model numbers are not known.
You have two timers.
You are replacing unknown electronic timer with unknown mechanical timer.
Intermatic timers and GE timers are different companies, and each makes many different timers
Each box timer has identification on inside of timer door.
Open following links to help identify timer and see wiring diagrams.

How do I wire a 220 volt two speed swimming pumpmotor using aground fault circut creaker


More information is needed.
Is the circuit breaker 240Volts or 120V?
Is the pump 240V?
What kind of switching timer is connected to pump?
What color are your wires?
Read information below and then add a comment.

Typically, the pump is 240Volts.
Pump is wired to mechanical timer with NO NC contacts for example GM40 series:
http://www.intermatic.com/products/ec%204%20layer/mechanical%20time%20switches/24%20hour%207%20day/gm40%20series%20multi-voltage%20time%20switch.aspx
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#GM
The timer sends power to one speed or the other speed but not both speeds at same time.
Timer can be mechanical or digital.
Mechanical timer is used if pump is supposed to be ON at all times.
Digital timer like P1353 is used to control pump more exactly.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#P1353
See example1 for 240V
http://waterheatertimer.org/images/P1353ME-2-speed-motor-500.jpg
Timer is rated or set for 240Volts.

GFCI protected 240Volt line leaves circuit breaker and goes to timer. Then timer and pump are both protected.

Pool pump cannot be turned off with timer switch. Pump runs constantly. I can turn off with breaker switch but not with switch on timer.


You posted under Intermatic EI200 series countdown timer.

Intermatic EI200 series is rated for 1/4 HP.
Check nameplate on motor for HP. Pool pump is probably 1 HP.
Open following link for countdown timer ratings:
http://waterheatertimer.org/Countdown-timer-horsepower-ratings.html
http://www.intermatic.com/products/timers/in-wall%20timers/electronic%20auto-off%20timers.aspx

Add a comment and say what kind of timer you are using and say specifically what you want timer to do, and I will locate correct timer for that specific need.

You can also add a contactor to the circuit.
Timer controls contactor, and contactor turns pump on-off.

You can replace the 133T1115A switch if that's the suspect part:

Other than the switch, the only other thing affecting timer would be the trippers.
