Operation is the same as described for 1 THEN 2 but with the priority sequence
reversed.
1 AND 2*
Variable Variable
In this mode both outputs are active in variable power mode. The available
excess power is shared between output 1 and 2, i.e. if 3KW of excess power is
available both outputs will receive 1.5KW. If the temperature of either output
reaches the set point then all available power will be sent to the other output.
Threshold Threshold
his mode both outputs are active in threshold mode. Once the programmed
level for output 1 is reached output 1 is turned on fully. If sufficient excess
export power is still available after output 1 has been turned on to reach the
programmed threshold of output 2 then output 2 will also turn on fully. Once
both outputs are active and the export power level becomes insufficient to
support both loads, output 2 is shed first.
1
(6/9/12KW)
Variable n/a
Operation in this mode allows the unit to operate in
combined loads of up to 12KW. In this mode only output 1 is available and up to
2 external contactors are required.
* Notes when operating in "1 AND 2" mode
1. Both outputs must be configured to operate in the same mode, variable or threshold.
2. When operating in variable power mode both output loads can be up to 3KW but each output
will only receive a maximum of 50% of its maximum rated value.
3. In threshold mode the total combined load of outputs 1 & 2 must not exceed 3KW when using
directly connected outputs. If using an external contactor for load switching the maximum load on
each output can be up to 16KW.
