I have just purchased the QC1102 motor to replace my old 1hp motor (K48L2PA105) I have a max e glas II pump (P4E6E-151L). The circuit breaker in the subpanel outside are double pole 15 amp (30 amp total). Is this the correct timer? I can't tell what timer I currently have as all labeling is gone.

Hi Cory, This is the correct timer that you can use with a double pole timer and the QC1102 motor.

I have a 1.5 HP pump for circulation and a 1.5 HP booster pump for my pool sweep. Will this control both if I wanted them to come on at the same time?

A     Answered on 7/29/2015 by Lennox H.

Hi, The Intermatic Timer 220 Volt Metal Enclosure can handle the two pumps if the max load does not exceed 40 amps.

How many on/off devices come with the unit? I am using this for my eletric hot water heater, I want the heater to come on around 5:00AM and off at 7:00AM, then on again at 5:00PM and off and 7:00PM. So I guess I'm asking can I program two on and off's or do I have to buy something else?

A     Answered on 12/26/2007 by Patrick P.

This timer comes with one "On" tripper and one "Off" tripper  but can accommodate up to 12 On/Off positions. So to accomplish the following "...come on around 5:00AM and off at 7:00AM, then on again at 5:00PM and off and 7:00PM" You would require the purchase of the timer which comes with 2 trippers, plus the purchase of one additional set of on / off trippers which you may view or purchase here

I have a T104R timer is this the proper replacement?

A     Answered on 2/17/2007 by Patrick P.

The T104R3 or the T104P3 are direct replacements for any T104 timer. The only difference between these two timers is that the T104R3 comes in a metal enclosure and the T104P3 comes in a plastic enclosure.

My pool pump motor indicates V115/230. Will thistimer accommodate the pool pump? Also,can you tell me the voltage on the clock motor?

A     Answered on 9/6/2006 by Patrick P.

Your pump can be wired either 115V or 230V If you have your pool pump wired at 230V than you would want to go with the T104P3 timer if you have the pump wired at 115V than you would want to go with the T101P3 timer. T104P3 timer has a 230V time clock motor and the T101P3 timer has a 115V time clock motor. You may purchase either of these time clocks through the following link
