Intermatic Pool/Spa Timer PF1102MT with Freeze Protection — 240 VAC, Adjustable Thermostat, 3 HP

The Intermatic PF1102MT is a compact 240 VAC timer with an integrated adjustable thermostat that automatically starts pool and spa pumps and heaters to reduce the risk of freeze-related plumbing damage.

Winterizing outdoor pool and spa equipment can be time-consuming and imperfect. The PF1102MT combines a mechanical timer with a temperature-activated switch so your circulation and heating equipment engage when air temperatures fall to the user-set threshold. Built for 240 VAC systems and motors up to 3 HP, this hardwired control is housed in a weather-resistant steel enclosure for long-term outdoor use.

How does the PF1102MT protect pool and spa plumbing?

When outdoor temperature drops to the set point on the built-in thermostat, the PF1102MT automatically powers the connected pump and/or heater. This prevents water in lines and equipment from freezing by maintaining circulation and adding heat as needed. Because it is hardwired and designed for continuous operation at 60 Hz, it provides hands-off protection through cold snaps.

• Activates pump and heater at user-adjustable temperature
• Supports motors up to 3 HP on 240 VAC installations
• Runs reliably at 60 Hz for consistent response

What are the installation and durability features I should know?

The PF1102MT arrives in a compact steel housing finished with an electrostatic beige coating to resist weathering and corrosion. Its small footprint fits tight mechanical areas while leaving access for wiring and timer adjustments. The unit is intended for fixed installation on 240 VAC circuits and must be installed according to electrical code and manufacturer instructions.

• Rugged 34/1000-inch drawn steel enclosure with protective coating
• Compact dimensions: approximately 9 3/8" H x 5 1/4" W x 3 5/8" D
• Designed for hardwired 240 VAC connections; follow local code

How do I set and use the thermostat and timer?

The PF1102MT features a user-adjustable thermostat that you set to the outdoor temperature where you want automatic protection to begin. Once set, the control will energize the connected equipment when ambient temperature falls to that level. The timer portion lets you integrate scheduled operation with the thermostat's freeze-protection override for flexible control.

• Adjust thermostat dial to desired activation temperature
• Timer coordinates scheduled runs with temperature-triggered operation
• Suitable for continuous or intermittent use depending on wiring and setup

Who is this for? The Intermatic PF1102MT is designed for pool and spa owners, service technicians, and property managers who need dependable, automatic freeze protection for 240 VAC systems. It suits installations where space is limited but reliable environmental control is essential, and for anyone who prefers a hardwired, weather-resistant solution to reduce freeze-related maintenance and damage risk. Professional installation is recommended to ensure electrical and safety compliance.
