PRM+ – intelligent 4.5 kW power and temperature controller

Professional controller for heaters, distilling, smoking, and brewing

PRM+ is an advanced power and temperature controller designed to control 230V heaters. The device combines the functions of a precise power controller with temperature control, probe support, staged programs, and an additional control output.

This device is for those who want more control over the process than a standard thermostat or simple power controller. The PRM+ is perfect for distillation, smoking, brewing beer, heating tanks, working with a pump, valve, stirrer, or additional heater..

The most important difference is that the PRM+ doesn't work like a standard thermostat on/off. The device allows smooth power regulation from 0-100%, which allows the heater to operate more stably, without sudden temperature "boosting."

Why is the PRM+ better than a standard thermostat?

A standard thermostat works very simply: it turns the heater on at full power and turns it off once the desired temperature is reached. In many processes, this causes large temperature fluctuations.

PRM+ works differently.

It allows you to smoothly adjust the heating power, e.g., 20%, 35%, 60%, or 100%. This allows for a smoother, more precise, and more repeatable process.

In practice, this means:

• more stable temperature,
• smaller heating peaks,
• better process control,
• greater repeatability of results,
• more convenient operation with high-power heaters.

This is especially important in distilling, smoking, and brewing, where temperature and heating method are very important.

Primary PRM+ Features

Smooth Power Adjustment 0–100%

The PRM+ allows you to adjust the heater power within the range of 0–100%. The user can precisely adjust the power to the current stage of the process.

This is useful when you want to:

• quickly heat the tank at the beginning of the process,
• lower the power later and run the process stably,
• limit excessive heating,
• adapt the heater's operation to a specific batch,
• obtain more repeatable results.

The power control can operate with a resolution of 0.25% or 1%, depending on the setting.

Power up to 4.5 kW

The controller can control power up to 4.5 kW, which allows it to work with more powerful 230 V heaters.

For example, it can work with a 2 kW + 2 kWheater system if the installation was performed correctly and in accordance with safety regulations.

This power reserve is well suited for:

• distillers,
• kettles,
• kegs,
• electric smokehouses,
• mash vats,
• heating tanks,
• liquid heating systems.

Graphic LCD display

PRM+ has a easy-to-read graphic LCD displaythat allows the user to view the most important operating parameters.

On the screen, you can control, among other things:

• current power,
• power setting,
• temperature,
• process settings,
• device operating parameters.

This is very convenient because you don't have to guess settings or rely on an inaccurate scale with a knob. The user sees specific values ​​and can easily return to verified settings.

Temperature Probe Support

PRM+ can work with one or two RJ45 temperature probes..

Probes are not included, so you can choose them for your application.

Working with a Single Probe

By connecting one probe, the controller can control the process temperature. It can maintain the set temperature or limit its maximum value.

This is useful, for example, in:

• distillation,
• smoking,
• brewing beer,
• heating tanks,
• controlling liquid temperature,
• processes requiring stable heating.

Working with Two Probes

The second probe offers much greater possibilities. It can be used as an additional measurement point or as a safety measure to terminate the process once the set temperature is reached.

Examples:

• in smoking – the second probe can measure the meat temperature and end the process when it reaches, e.g., Ta = 80°C,
• in distillation – the second probe can measure the temperature in the keg and end the process when it reaches, e.g., Ta = 90°C,
• in beer brewing – the second probe can monitor another point in the system, e.g., the tank or flow.

This is a very practical solution because the user does not have to constantly monitor the process manually.

Uses in Distillation

PRM+ works very well in distillationwhere power control is crucial.

At the beginning of the process, higher power can be used to bring the system up to speed faster. Once the appropriate conditions are achieved, you can reduce the power and conduct the process more smoothly and stably.

PRM+ helps:

• stabilize the output,
• limit sudden heating spikes,
• better match the power to the equipment,
• control the temperature,
• protect the process from overheating,
• automatically stop the operation when the alarm temperature is reached.

The second probe can be used, for example, to monitor the temperature in a keg or another important point in the process.

Use in smoking

PRM+ is also suitable for electric smokers.

During smoking, maintaining a stable chamber temperature and controlling the temperature inside the product is crucial. Simply setting the heater power is often not enough, especially when the load is large, the chamber has a large capacity, or the smoker is operating on colder days.

PRM+ allows you to:

• control the heater power,
• maintain the chamber temperature,
• limit the maximum temperature,
• measure the meat temperature with a second probe,
• terminate the process once the desired product temperature is reached,
• achieve more repeatable results.

This is very convenient when smoking:

• hams,
• bacon,
• sausages,
• pork neck,
• pork loin,
• poultry,
• fish,
• cheese.

Thanks to the second probe, the user can monitor not only the temperature of the smoker, but also the temperature inside the product. This makes a huge difference, because only the temperature inside the meat shows whether the product has actually reached the desired condition.

Beer Brewing Applications

PRM+ is also a very good choice for beer brewing..

The device allows you to create brewing profiles consisting of up to 10 stages, where each stage can have a specific time and temperature.

Additionally, you can save 5 recipes, making it very easy to repeat proven processes.

This is especially useful for:

• mashing,
• maintaining temperature,
• changing temperature intervals,
• working with the mash tun,
• operating the pump or agitator.

Instead of monitoring everything manually, the user can prepare a profile and run the process much more conveniently.

Brewing Profiles – Up to 10 Stages

PRM+ allows you to program up to 10 work stages.

Each stage can include:

• a set temperature,
• a specific duration.

This allows you to create a complete process flow, e.g., for beer brewing or other applications requiring multiple temperature steps.

This solution ensures high repeatability. If a recipe works once, it can be saved and used again.

5 recipe records

The device allows you to save up to 5 recipes.

This is very practical if you work with different processes or different products.

For example, you can save separate settings for:

• different beers,
• different batches,
• different operating temperatures,
• different heating systems,
• different technological processes.

This eliminates the need to re-enter everything each time.

Additional 230 V / 1 A control output

The PRM+ has an additional control output that can be used to operate auxiliary devices.

It can control, among other things:

• valve,
• pump,
• a stirrer,
• a Braumeister-type system,
• an additional heater from the second phase via a contactor.

The output has the following parameters: 230 V / 1 A.

This is a significant advantage because the controller can control not only the heater itself, but also an additional process element. This makes the entire system more automatic and convenient.

Adjustable power limits

PRM+ allows you to set minimum and maximum operating power.

This is very practical because the user can limit the controller's operating range to values ​​that are safe and useful for a given process.

Examples:

• You can limit the maximum power to prevent the heater from working too aggressively.
• You can set the minimum power to prevent the process from dropping below the desired level.
• You can adjust the controller to a specific heater, system, or tank.

This is useful for distilling, smoking, or brewing beer.

Forced Cooling

The device has a built-in fanwhich provides forced cooling.

This is important when operating at higher power levels and with longer operating times. This makes the controller better prepared for real-world operation with heaters.

Cooling helps maintain stable electronics and increases user comfort.

Protections

The PRM+ is equipped with:

• overcurrent protection,
• thermal protection.

This is especially important when working with high-power heaters.

Protections increase operational safety and protect the device in the event of abnormal operating conditions.

Plug-in installation

The PRM+ is easy to connect and use.

The device has a power cord 180 cm with a plug and a socket on the housing. This makes installation simple, and initial start-up does not require any complicated work.

This solution is good for those who want to quickly set up the set and use the controller immediately.
