Other Wiring Options

The TEC 100/200 has three control relays. On the TEC 100 the left hand relay
is the

Plant Relay

which may be used to control a circulating pump and the

right hand relay is the

boiler control circuit

. The centre relay (Tec 100 only)

make and breaks on RTN/HW settings and may be used to control a HW pump,
solenoid etc, see Fig 4. On the TEC 200 the left hand relay is the

Plant Relay

the middle relay is
