Failed Intermatic DIY Mod Solution, How?

[jayinc11]

My intermatic's auto function timer went out about 3 years ago during a freeze. There's an on/off switch in the line to the timer I have been using to operate the pool. To replace the daily walks I want to spend as little as possible to install a mod if I can away with that instead of replacing the failed unit. My idea is to install a wi-fi smart plug between the on/off switch and the timer such as this or this one. I am handy but I need guidance on making sure power ratings/amps/wattage etc of these devices matches.


Which wifi plug will handle my pump's power requirements or what should I look for?


PLUG-1
Working voltage:AC110~240V
Max power:2000W(resistance loading)
Working current:MAX 10A
Colorearl White
Material:ABS flame retarding polymer
Standard:5 holes standard,China
Wireless frequency:2.412~2.484GHz
Wireless IEEE standards:WiFi 2.4GHz b/g/n
Security type:WEP/TKIP/AES
Security regime:WEP/WPA-PSK/WPA2-PSK
Wireless consuming:≤0.3W
Temp:-20~40℃ Humidity:≤80%


PLUG-2
Input voltage: AC 90-265V 50/60HZ
Max Power rating: 2200W
Maximum current:10A
WiFi amplify: 15DBM
WiFi standard: 802.11B/G/N


PLUG-3
Operating Voltage: AC power input AC110V ~ 240V
Output Power: Maximum output power 3500W
Output current protection action: ≥ 16A
Plug mating cycles: > 5000


Here is my main pump and the rarely used polaris pump

Here is the setup


The second solution I have in mind is to add one of those timers from Lowes, but same idea, just add a plug between the on/off switch and the intermatic. I just don't know the right one, see here.

You can get just the timer internals:

As Mark said, you can buy just the internals of the timer. Even further than that, if you know which part is bad (i.e. timer motor) you can buy parts for it.

The problem with those switches listed is that they're usually not rated for motor (inductive) loads.

You also don't tell us whether the pump is wired for 120 volts or 240 volts. If it's 240 volts the idea of installing a plug won't work.

I agree with the others, just fix the Intermatic ... they are darn near bulletproof, a little odd that a freeze would have affected it.

The unit is an intermatic PF1102T model, from the info it looks like a 240V. Here is the pic (won't post here exceeded my limit error)

I think it takes a different type of an internal mechanism, correct?
Or can it take the one you posted?

Also can a PF1102MT model's (here below pic) mechanism replace the one I have now-PF1102T?

I was going by the timer on the left in the picture. You can get the PF1102 internals as well but it is a lot more because of the freeze protection.

If it's the basic intermatic timer (the one on the left), most failures are just the clock motor. A new one can be had for less than $20.

Is this what you were referring to? -> here
If so how would I know the correct one for my timer?

Get the model number of the timer, then Google is your friend.

I thought you needed to replace the timer on right which is electronic. So I think you will need to replace the whole thing.

Oops that is correct. Senior moment. The one on the left is for the polaris, works great. The electronic one on the right is the troubled one.

I appreciate the input guys. I hope I don't come off as one who won't follow the advice already given. I am on a tight budget. I guess what I am wondering is is there a way at all, to put this pool pump back on a functional safe timer for a budget of <50 bucks, be it a substitute...a mod...? Such as this woods timer. Can this work...i.e. match the power requirements of my pump (pump pic is at the beginning of this post) See here -> Woods Timer http://s31.postimg.org/sm1w0f197/IMG08.jpg

If you just want to replace the timer with a basic intermatic 220v timer, they can be had for about $50.

It just won't have freeze protection like your old timer.
