Enviro C-11089 - Manual (Page 8)

Operating Instructions
The Sonnet is designed to gradually lower or raise the flame as is needed in application. It normally does
not just turn on and off. This is very dependant on the size of the room the unit is located in. During the
first several operational cycles the electronics go through a learning process that establishes how the
system will react to the environment it is in. It does so by determining the amount of time it takes for the
temperature to rise 1°. It does this several times to maintain consistency. Once this has been learned it
will respond the same way each time it is used. It is possible to relearn by removing the batteries from
the receiver and re installing the batteries after several minutes have past. If there is no call for heat and
the unit is in the lowest operation condition the valve will turn the burner to the off position. When there
is a subsequent call for heat the burner will turn back on at the low setting. Should this not be adequate
in application the valve will open more to allow more gas flow to the burner.
R EMOTE H ANDSET C ONTROLS :
The remote handset included with this unit has a thermostat in its control system and a design feature
that will turn off the unit if there is a no communicate condition caused by the handset being removed
from the normal range of operation (up to 20-25ft (6.1-7.6m)) or a low battery condition in either the
receiver or the hand set. If one or more Sonnets are to be installed, confirm that the remote control signal
codes are different for each unit, refer to M AINTENANCE AND S ERVICE - C HANGING R EMOTE H ANDSET C ODE .
Setting the Time
1. The display will flash after either: (a) Installing the battery or (b) Simultaneously pressing the (up
arrow) and (down arrow).
2. Press (up arrow) to set the hour and the (down arrow) to set the minute.
3. Press OFF to return to manual mode or simply wait and it will
automatically return to the manual mode.
Setting °C/24 hour or °F/12 hour Clock:
Press OFF and (down arrow) until display changes from Farenheit/12
hour clock to Celcius/24 hour clock and vice versa.
Automatic Pilot Mode:
If there is no transmission from the handset to the receiver within a six (6)
hour period, the unit will go to standby (pilot) mode.
Adjustment of Flame Height:
In standby mode: Press (up arrow) to increase flame height. Press
(down arrow) to decrease flame height or to set appliance at pilot flame.
For fine adjustment tap the up/down arrows.
Mode Settings:
TEMP MODE – Daytime Temperature Mode (appliance must be in standby mode; pilot ignited):
The room temperature is measured and compared to the set temperature. The flame height
is then automatically adjusted to achieve the Daytime set temperature.
TEMP MODE – Nighttime Setback Temperature Mode (appliance must be in standby mode;
pilot ignited): The room temperature is measured and compared to the Nighttime Setback
temperature. The flame height is then automatically adjusted to achieve the Nighttime
Setback temperature.
