Pool timer Sir, I have an intermatic pool timer that is rated for 120/240 volts. The pump is wired for and receiving 220v/40amp. However, the timer portion is rated for 120v. Do I need to get another timer that is rated for 220? The directions are rather ambiguous. Thanks for any help.

RT3 series has T104 240 volt timer -or- T103 120 volt timer, -plus- low voltage transformer for pool light.
The circuit breaker can be used for transformer, or another outlet or nearby light etc, or it can be used for a T103 120 volt timer.
To trace the wire back to breaker box.... open you main panel and start turning off breakers one at a time and label the panel.
See if you have single breaker or double breaker supplying power to pool equipment.

Verify that the clock motor is 220v. On the posts where the supply wires (line) and pool motor wires (load) they should each have a post for each of their two wires. If you do not have four posts, this is NOT a 220v timer.

1) Not likely the timer is problem, unless there was fire or overheating in timer box. Use nose and eyes to inspect for signs of high heat.

2) Eliminate timer as suspect:
Move wires on timer to test if timer relays have gone bad.
Move terminal 4 to terminal 3
Move terminal 2 to terminal 1

3) Check watt rating of Hayward pump, and voltage.
1Hp motor at 240Volt draws 8 amp, and can draw 6 to 8 times that amount when starting. Up to 100 feet, should be at least 12 gauge wire and double-pole 20 amp breaker. Over 100 feet, 10 gauge wire and 30 amp double-pole breaker is best.

4) Intermatic T104 240V timer is rated 40 amps
Can safely handle 1 Hp motor without nearing heat-rating capacity of timer

5) Make sure the motor is wired correctly for 240Volts.
If motor is wired for 120, and 240 is applied, then tripped breaker can result.

No. I don't have a wiring schematic without knowing what voltage you are using, specifically what Intermatic timer you have, specifically what wires you have coming from breaker box, what wires are on the pump, and what pump rating plate says, what the wiring diagram shows on side of pump, whether you are wiring a 2-speed pump to a single-speed timer, specifically what is the polaris timer clock, and why this pump needs two timers if that's what you mean.
Add a comment with specific information so electrician is not guessing.

Open following link for 240Volt T104 timer wiring diagram.

Paragon no longer makes timers or parts, except defrost timers.
Typically, defrost timers are not used for pools.
Open following link to possibly identify timer and tripper part number.

If you want a new timer for pools, Intermatic makes the T101 120Volt and T104 240Volt:

If you want T100 series timer with fireman's switch that turns off heater 10 minutes before turning off pump:

If you have energy-saving 2-speed pool pump, and thermostat and pool light, then buy P1353 digital timer with enclosure. Enclosure and timer sold together as P1353ME.

P1353 is not easy to wire or program for novice, so you can add a comment or repost question on fixya and I will catch it.

Sounds like 240Volt WG1573 clock motor has gone bad and needs replacement. But more checking is needed.

You posted under T2100-4R which is 60 amp Intermatic control panel with a single T104M 240Volt timer mechanism.
All Intermatic timer mechanisms can fit into same control center, so you can possibly have different timer mechanism inserted into the T2100-4R control center.
The control center can have up to 4 circuit breakers.
Instruction manual shows that timer can also have fireman's switch that is wired to pool heater and causes pool heater to turn off 20 minutes before pool pump turns off.

(1) First thing: If you have T104 mechanism, do a troubleshoot run-down to see if trippers, clock motor, or wiring are suspect:
http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timer.html

(2) Next would be to check the circuit breakers for loose wires, burned connections, or the smell of burning or crackling sound that says breaker is loose on the busbar.

(3) Check for loose wiring on T104 and test circuit:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
(a) Push the manual override lever to OFF position and test across terminals 1 and 2 and then across terminals 3 and 4 to make sure timer is turning off power to pump. Both tests should show 0 volts.
(b) Push manual override lever to to ON position and repeat test above. Both tests should show 240 volts.
If the test fails, then buy new T104M timer mechanism.

(4) If the T104 timer is turning off both lines in the 240Volt circuit, then pump cannot turn on since neither wire is Hot.
However if your T104 timer is actually a T101 timer or if timer has different wiring, where timer is turning off only 1 leg and not both legs of 240Volt circuit, then pump has one hot wire available and a short to ground could cause pump to turn on unexpectedly.

The instructions are available from Intermatic if you click on the below link.

http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/t104%20-%20english.ashx

240 volts will have two 120 volt lines and a ground(green or bare) or neutral (white) wire.

If your system is 240 volts the Red and Black wires are hot should be individually connected, one to terminal 1 and the second color to terminal 3. The load or pump in your case should be connected to terminal 2 and 4. If you want to wire a switch to the load you need to decide on how you want the switch act, 1) as an auxiliary on 2) as an emergency off. If you want an auxiliary on for the pump, you need a DPDT (Double Pole Double Throw) 40amp switch (what should be in the house). Run the appreciate gage of wire (AWG 8 for 40A) from terminal 1 to one pole of the switch and a wire from terminal 3 to the second pole of your switch. Next run wires from the switch contacts from the two remaining switch terminals to terminals 2 and 4 on the timer matching the Red side on the switch to and Red on the timer and Black side on the switch to Black on the timer. The timer will control the function of the pump, and the switch will turn the pump on when the timer is off. If you only have two hot wires coming from the house attach them to terminal 2 and 4. If you want an emergency stop you need to wire a second DPDT 40amp switch and disconnect the load wires from terminal 2 and 4 and connect each one to the opposite poles of the switch. Using the correct gage of wire you need to connect a red and black wire to the two separate terminals of the switch. When the switch is off the pump will not work but the timer will keep the current time. The color of wires may not be the same in that situation you will need a multi meter to identify the wires.

I need a little more information on the pool sweep timer. Are you using the same timer or just the power? Is the power 120 or 240 volts? When do you want the pool sweep to be active?

You will need a timer that is rated for the amps of your heat pump. Then you will bring your power from panel box into your line on timer and then from load on timer to the heat pump

The two wires are interchangeable.
