Turbotemp Gas Heater Remote Control Connections
1. Switch off power to heater at main circuit breaker panel.
2. Unbolt and remove the access door panels.
3. Open control box cover (see Figure 23).
4.
To connect a 2-Wire Control (such as Waterco Aquamaster™)
or a timer:
• Remove the factory installed jumper from the Fireman’s
Switch terminals.
• Connect wires between the Fireman’s Switch terminals
on the heater and the relay. Connect wires from the
controller or timer to the Fireman’s Switch. Controller,
timer or relay should be sized to handle 24VAC at 0.5
Amp (because it will be completing the 24VAC control
board circuit on the heater as shown in Figure 24).
DO NOT apply line voltage to the Fireman’s Switch
terminals. Use 1mm
2
minimum cable with a minimum
1.2 mm thick insulation rated for a temperature rise of
at least 105°C.
• Knock-outs are provided to route the
wires through the bottom of the control
box and past the junction box.
5. Close control box cover.
6. Re-install the access door panels. To control
heaters that are operated in parallel, connect
wiring at same locations on heater Control.
It is imperative that each control circuit is
isolated from the other control circuits, to
avoid that current will flow from one heater to
another through the control circuits.
NOTICE:
The fuse for the Fireman’s Switch
is a 24V 1.25 Amp 31.75 mm x 6.35 mm fast
blow fuse, which is commonly available.
Waterco Heat Pump Remote Control Connections
1. Switch off power to heat pump at main circuit breaker panel.
2. Unbolt and remove the front access panel.
3. Open control box cover.
4. To connect a 2-Wire Control (such as Waterco Aquamaster™) or a timer:
• Locate the pressure switch on the bottom plate of the electrical enclosure.
• Cut one of the cables connected to the pressure switch. Connect the two wires from the
Controller Normally Open Contact to the two ends of the cut cable and make electrically
safe. Controller, timer or relay should be sized to handle 24VAC at 0.5 Amp (because it will
be completing the 24VAC control board circuit on the heater as shown in Figure 24). Use
1mm
2
minimum cable with a minimum 1.2 mm thick insulation rated for a temperature rise
of at least 105°C.
5. Close control box cover.
6. Re-install the access panel. To control heaters that are operated in parallel, connect wiring at
same locations on heater Control. It is imperative that each control circuit is isolated from the
other control circuits; to avoid that current will flow from one heater to another through the
control circuits.
