AUTOMIX 20 controls both floorand radiator heating systems.

To set the supply water limiter at45°C or below makes the

AUTOMIX select a slower programespecially designed to regulatefloor temperatures. Setting the

water limiter above 45°C providesa control unit ready to regulate

radiator heating systems.

has no graph to be setA temperature control with an

outdoor sensor requires a graph setting. To select the proper graph

in advance is very difficult. It usually involves a period of trial and error causing fluctuations in

the indoor temperature. AUTOMIX 20 needs no graph

selecting. The desired temperature is to be set at the room thermostat and that’s it.

systems and radiator systems.

has freeze protectionFreeze protection mode is

obtained by setting the room temperature to +5°C. The night

setback function does not operate while AUTOMIX 20 is

in freeze protection mode.

is simple to install andto operate

AUTOMIX 20 is delivered factory wired. The main wire, the supply

water sensor and the adapter have plug-in connections. The room

thermostat and the valve motor are connected through the main wire. The supply water sensor and the

adapter are to be plugged into the valve motor. AUTOMIX 20 can’t

be installed the wrong way.

is an advanced electronictemperature control

All settings are made at the room thermostat. Through impulses from the room sensor, changes of room temperatures are forwarded to a microprocessor which directs the

motor to keep the plug of the mixing valve in the position that corresponds to the heat required

in the house.

factors in the houseAUTOMIX 20 responds to the temperature changes in the house caused by solar gain

through the windows, by internal heat gains or by outside wind

for which outdoor sensor controls can’t compensate.

setbackA night setback of 1°C, 2°C or 3°C for 7 or 9 hours is easy to

program. AUTOMIX 20 will repeat the setting every 24 hours until a

different setback program has been entered.

kinds of temperature changes in the house caused by e.g. solar heat through windows, outdoor winds etc. The microprocessor

compensates for such changes of temperature which a system with

an outdoor sensor cannot do.

• TERMOMAT 2 measures the temperature difference between a prima-ry and a secondary storage tank. The charging pump is controlled sothat the secondary tank keeps its energy with a maintained layeringfor as long as possible. When both tanks are out of energy a relayautomatically starts an optional additional heat source. A digitaldisplay shows the temperatures T1, T2 and T3.

• The pump starts charging from the primary to the secondary tank assoon as temperature T1 is above the selected value or temperature T2is below the selected value.

• The pump stops when temperature T3 has reached the selected value,temperature T2 is higher than T1 or T1 is below the selected value.

• The relay automatically starts the additional heat source when tempe-rature T1 drops below the selected value or T3 is 3°C below theselected value. In this case the pump does not run.

• The relay does not work when temperature T2 is higher than theselected value.

• With TERMOVAR thermic valve the temperature of the secondary tankcan be limited to 45°C, 55°C, 61°C, 72°C or 80°C.

See TERMOVAR LOADING VALVE brochure.

• TERMOMAT 3 measures the temperature difference between a storagetank and a boiler. It controls the burner and the charging pump. Whenthe storage tank is out of energy, burner and pump start working. Adigital display shows the temperatures T1, T2 and T3.

• The burner starts when temperature T2 drops below the selected value.

• The burner stops when temperature T3 is higher than the selected value.

• The pump starts when temperature T1 is above its selected value andabove temperature T2.

• The pump stops when temperature T3 is higher than the selected value.The pump continues to run for 3 min before stopping.

• A system with a TERMOVAR loading unit ensures a minimum returnwater temperature into the boiler, which eliminates the risk ofdestructive thermal shock and prolongs the life-time of the boiler.

2. The loading phase

The thermostat element in the loading unit is affected by the temperature of the water circulating from the boiler to the loading unit. (See table be-low.) The thermostat element starts opening at 61/72/80°C * and is fully open at 73/84/92°C *. When the temperature in the boiler reaches61/72/80°C * the thermostat element opens and allows return water from the storage tank to be mixed with supply water before it returns back tothe boiler. The temperature of the supply water determines the working position of the thermostat element.A balancing valve in the loading unit regulates the internal flow of the supply water. The working position of the thermostat element determines theclosing position of the balancing valve. (See table below.) When the temperature is 67/78/86°C * the thermostat element starts to close the balan-cing valve. This causes a higher flow of return water into the boiler. When the temperature reaches 73/84/92°C * the thermostat element is 100 % open and the balancing valve is 100 % closed.

* depending on selected opening temperature

measures flue-gas temperature. The pump will start when

the boiler is fired up and stop when it has ceased to fire.

The boiler water is circulating to the loading unit and back

while the temperature of the boiler is rising.

TERMOVAR LOADING VALVE

TERMOVAR LOADING VALVE is an automatic thermally operatedloading valve for solid-fuel boiler/storage tank installations, whereheating and domestic hot water are taken from the tank.

TERMOVAR ensures a minimum return-water temperature in theheating boiler, which increases the efficiency, prevents tarring andconsiderably prolongs the lifetime of the solid-fuel boiler.

TERMOVAR eliminates the risk of destructive thermal shock to bothsteel and cast iron boilers. TERMOVAR thermally operated loadingvalve renders a more effective burning and is therefore a necessarypart of a solid fuel installation with a storage tank.

TERMOVAR LOADING VALVES may be selected with 45°C, 55°C,61°C, 72°C or 80°C fixed opening temperatures.

The valves can be delivered factory mounted in any position andwith other temperatures on request.

INSTALLATION:TERMOVAR installed in the supply water pipe.

FUNCTION:When the solid-fuel boiler has reached the selected temperature the thermal valveopens. Supply water from the boiler is loaded to the storage tank. Return waterfrom the storage tank is mixed with supply water before flowing back to the boi-ler. The loading continues as long as the boiler is being fired. A balancing valveis to be installed between boiler and loading valve.

TERMOBAC:When the loading of the storage tank is completed the circulation pump will shutoff. The TERMOBAC will now prevent self-circulation from storage tank back toboiler. In case of power or pump failure the TERMOBAC will open automaticallyfor self-circulation.

LOADING PUMP:The loading pump should be controlled by a thermostat which measures boilertemperature. The pump will start when the boiler is at operating temperature andstop when the boiler drops below this temperature.
