TEC 100 - Setting System Maximum Flow Temperature

11
Establishing the System Maximum Flow Temp
Switch on the power to the TEC 100/200.
1. Set the Bypass Switch to the bypass position.
Allow the heating system to cycle twice at the normal winter setting of the
boiler thermostat (see plant engineer, caretaker, maintenance manger etc to
establish winter thermostat position).
2. The display will show:
FIRING Tu 10:05

Current Mode
Set Temp
Actual Flow Temp
Actual Return / HW Temp
Actual External Temp
3. When the actual Flow Temperature exceeds the Set Temperature, the display
will change:
TEMP.SET Tu 10:05
S57 F58 R48 E05
4. When the boiler has cycled twice with the TEC 100/200 in bypass, observe the
actual flow temperature as shown on the display:
In this example, the winter setting for the heating system (TEC 100/200
maximum flow setting) should be set to 72ºC (73ºC - 1ºC).
The Boiler Thermostat should now be set to a higher setting to ensure correct
operation of the TEC 100/200.
