INTERMATIC EH40 Timer Water Heater

Intermatic EH40 electronic water heater time switch is suitable for managing the operation of water heaters and optimising energy usage by programming specific ON / OFF schedules in agriculture feeders, greenhouse misting control and water heater control. This time switch is used in commercial and industrial settings to ensure efficient water heating during periods of demand, such as peak usage hours.

Working Mechanism:

• Interaction with the time switch occurs via its display and user interface. Using the buttons and display, users can input their preferred ON / OFF timings for each day of the week.
• An internal clock within the time switch accurately maintains track of time, encompassing minutes and seconds.
• The time switch is integrated into the water heater's power supply line. Upon scheduling an ON event, the time switch dispatches a signal to close the circuit and channel power to the water heater. In the case of an OFF event, the time switch emits a signal to open the circuit, disconnecting power from the water heater.
• External to the time switch is an override switch, offering manual control over the water heater's operation that supersedes the programmed timetable. This proves beneficial when unexpected changes in hot water demand arise.

Features:

• It features precise control with 42 ON / OFF events per week, allowing versatile scheduling options.
• This timer comes with a replaceable battery backup, ensuring uninterrupted functionality even during power outages.
• It allows to-the-minute programming and time-keeping accuracy to ensure precise operation.
• This timer provides an external override switch for manual control when needed.
• It is equipped with an LED load indicator that displays the device's status at a glance.

Standards and Approvals:

Frequently Asked Questions:

Q. Is it good to have hot water on a timer or constant?

A. Leaving the hot water heater on continuously is preferable to turning it on and off intermittently. However, you don't actually need to constantly heat your water. Hot water kept in a tank heats up by your boiler or immersion heater.

Q. What is the purpose of a water heater timer?

A. A water heater timer is a device that regulates when a water heater is switched on and off. Instead of keeping hot water throughout the day, your water heater will now only give it when it is set to do so.

Q. What is the operating temperature of this Intermatic EH40 water heater timer?

A.This Intermatic EH40 water heater timer offers an operating temperature range of -40 to 104 degrees F.

Q. What is the duration of the programming cycle in this Intermatic EH40 timer?

A. This timer offers a 7-day programming cycle for tailored automation.

Q. Does this Intermatic EH40 electronic water heater timer provide an override switch?

A. Yes, an override switch enables the bypass of malfunctioning field inputs to aid in startup. This override will be automatically deactivated once the field input returns to normal or reaches a preset time limit, whichever comes first.

Q. Is it preferable to keep hot water continuously on or use a timer?

A. It's actually more efficient to avoid leaving the hot water heater running, contrary to a common energy-saving misconception. Continuously heating water isn't necessary. Immersion heaters or boilers warm up water stored in a tank, and maintaining a continuous heating cycle isn't always the most energy-efficient approach.
