Intermatic T101P201 – Frequently Asked Questions

1) Can the Intermatic T101P201 time switch be mounted outdoors next to the pool equipment pad?
Yes. The T101P201 comes in a Type 3R plastic enclosure, which is the outdoor rating for rain, sleet and ice, so it can go on an exterior wall or an equipment pad without a separate weatherproof box. Note it is a plastic enclosure, not metal, so it will not be the choice where a spec calls for a metal Type 3R cabinet.
2) What voltage does the Intermatic T101P201 mechanical time switch run on, and will it work on a 240V pool pump circuit?
The T101P201 is a 120 VAC, 60 Hz unit with an SPST switch, so it belongs on a 120V circuit. It is not the part for a 240V two-pole pump load; that needs a DPST time switch instead. Check the voltage at the equipment before ordering, because a 120V clock motor wired to 240V is a destroyed timer.
3) What does the pool heater protection on the Intermatic T101P201 actually do?
It guards the heating equipment during start and run cycles, so when the timer cuts the pump the heater is not left firing into dead water. If you are timing a pool pump that shares a circuit with a heater, that is the reason to pick this version over a plain 24-hour time switch.
4) What model do I order for the Intermatic gray outdoor 120V pool timer with heater protection?
Order Intermatic part number T101P201. That is the 24-hour, 120V SPST mechanical time switch in the gray Type 3R plastic case with pool heater protection. The T101 base number is the 120V single-pole clock, and the P201 suffix is the enclosure and heater-protection package, so a bare T101 mechanism is not the same order.
5) How much wall space do I need for the Intermatic T101P201 timer enclosure?
Allow for a case measuring 10 x 6.5 x 4 inches (height, width, depth), plus room to swing the cover and to bring conduit into the bottom of the box. That footprint is what decides whether it fits between the pump and the heater on a tight equipment pad.
6) How many on/off cycles a day can I set on a 24-hour mechanical time switch like the T101P201?
Up to 12 ON/OFF operations per day, set with trippers on the 24-hour dial. That covers a pool pump running two or three filtration blocks a day, or a circulation pump cycling on the hour. The schedule repeats every 24 hours, so there is no separate weekday and weekend program on this one.
7) Is the Intermatic T101P201 only for pools, or can I use it to time a pump or motor on a building?
It is rated for heater thermostat control, motor control and pump control, so it is not pool-only. Property managers use the same box to schedule circulation pumps, exterior motors and HVAC-side equipment. The limits are the ones above: single load, 120V, one repeating daily schedule.
8) Can I wire more than one load to the Intermatic T101P201 timer terminals?
The switch controls a single load, but the teeter-type terminals accept multiple conductors, which is how installers land more than one wire per terminal on a shared circuit. Do not read that as two independently switched circuits, it is one SPST contact.
9) Why choose a mechanical time switch over a digital timer for a pool pump?
A mechanical 24-hour switch has no electronics to lose a schedule when the power blips, and the trippers are set by hand on the dial, so any maintenance tech can change the run times without a manual. The trade-off is that the clock motor is fed from the same 120V line, so an extended outage shifts the dial and the time has to be reset. Pick digital if you need astronomic (sunrise/sunset) switching or separate weekday programs.
