Laddomat MR

• A Laddomat MR can control in many different ways, partly making it easier to have it in stock, partly easier to learn one and the same control with the settings, connections and the adjustments that are possible.
• Removable terminals in the connection centre make it easier to connect sensors and pumps.
• The display provides an overview of relevant temperatures and settings, as well as what is currently operating.
• Possibility of connection up to 4 sensors to read temperatures in the display.
• Submersible tubes and/or materials for sensor tube assembly are always included according to the specification for best functions.

Scope of delivery:

Laddomat MR control panel with 1.5 m communication cable. Connection centre. 4 x sensors with 3 m cable. DIN rail for wall mounting the CC. Screws and plugs for installing the CP and CC are also included.

Other control options:

Sys 0
Display of up to four different temperatures.

Sys 60
Start of circulation pump plus display of boiler temperature and three different
tank temperatures.

Sys 70
Differential control with two temperature sensors.
Examples of areas of use:
Charging from solar collectors when the solar collector is warmer than the tank.
Charging from one tank to another, when the first tank is warmer than the second.
Additional heating can be started if the temperature T2 is too low.

Sys 90
Thermostat function, where one, two or three relays can be controlled from one
temperature sensor each.
Example of area of use:
To start circulation pump and additional heating.

Sys 99
”Free” function, where optional temperature sensor is used for optional relay.
Up to eight different settings are possible.
Examples of areas of use:
When the sensor T1 is warmer than 80°C, a charging pump is started.
When the sensor T1 is colder than 60°C, a recharging pump is started.
When the sensor T1 is warmer than 95°C or colder than 35°C, an alarm is sent.
