Honeywell DTC 100/4 TD User Manual

DTC 100/4 TD
5
VDR resistor
Thermo-shrinkable
tubes
ELECTRIC CONNECTION:
Grounding wires
should be connected
to special terminal
pins situated on right
side of terminal strips.
WARNING:
Boiler control should be performed behind the main switch for burner but in front of boiler
thermostat. Care must be taken that differential thermostat and boiler connection are
performed at the same phase otherwise inter-phase contact can occur.
SENSOR INSTALLATION IN COLLECTOR:
Install it as immersion sensor in
collecting pipe at the top of the
collectors in provided sleeve
For cables longer than 15m we
recommend over-voltage protection
with VDR resistor.
