AGS WTM Installation, Operation & Maintenance

Valve Outputs

Use grounding terminals for gas valves not considered class II apparatus!

Connecting two valves to both mains 120V~ and 24V~ simultaneously is considered misuse – use only one

valve output!

A water solenoid valve should be powered using one of the terminals marked [VALVE OUT].

Terminals offer control via 100-120V~ or 24V~. When wired to a normally closed water solenoid valve, the

WTM controller can be used to isolate the water supply when water temperature is outside of allowable Max

and Min temperature settings.

BMS Relay Output

Connections are available on the board for Building Management Systems. [NO - Normally Open] [C -

Common] [NC - Normally Closed]. This is a relay that changes state in alarm / water off.

0-10V Analog Output

A single 0-10V output is scaled to the PT100 temperature sensor as follows.

32°F

50°F

68°F

86°F

104°F

122°F

140°F

158°F

176°F

194°F

212°F

10V

PT100 Temperature Sensor Input

Adjust Min and Max Allowable Water Temperature

Turn On the dipswitch [SET] located on the circuit board to program Min and Max water temperature.

Using Up and Down arrows located on the front fascia select required Min temperature.

Press OK and repeat for Max temperature. Turn Off the dipswitch [SET] to exit temperature

programming menu and save.
