REMOTE CONTROLLER
Controls to operate the fan speeds and thermostat are on the front face of the controller.
ON/OFF AND FAN SPEEDS
The switches on the left hand side control the ON/OFF and fan speed operations.
The lower left hand switch is the ON/OFF control. The green neon is lit when the switch is 'ON'.
The upper left hand switch operates the fan speeds.
The fan speed switch gives minimum fan speed at position , medium fan speed at position and maximum fan
speed at position .
TEMPERATURE CONTROL
The right hand knob selects temperature, which is automatically controlled by the thermostat in the remote control
housing; the range is factory set from 17°C to 30°C.
By turning anti-clockwise, lower room temperatures are maintained; by turning clockwise, higher temperatures.
The white neon is lit when the unit is in cooling mode.
The amber neon is lit when the unit is in heating mode (if the system includes a heat pump outdoor unit).
Neither neon is lit when the thermostat is between cooling and heating.
User Maintenance
Isolate at the mains before commencing any maintenance work.
In order to maintain maximum efficiency it is important that the filter behind the return grille is cleaned regularly; this will
normally be every two to three weeks.
SWITCH OFF THE UNIT AND ALLOW THE FAN TO
STOP
Remove the filter from the housing.
Wash the filter (in tepid water) and dry before use.
Alternatively tap the filter gently to remove dust or vacuum
clean.
THE UNIT SHOULD ALWAYS BE USED WITH A
FILTER. FAILURE TO DO SO WILL CAUSE A
DECLINE IN UNIT PERFORMANCE AND MAY
RESULT IN MALFUNCTION.
We recommend that in order to prolong the life and
maintain performance of your
'Marstair' units you arrange
a regular service contract with your TEV Ltd.
installer/dealer.
